Introduction

In mathematics, the concept of function transformation is a crucial aspect of understanding and working with functions. One of the fundamental transformations is the horizontal shift, which involves shifting the graph of a function to the left or right by a certain value. In this article, we will evaluate the function $ h(x+a) $ for the given function $ h(x) = 5x^2 + 3x $, where $ a $ is a constant value.

Understanding the Function $ h(x) = 5x^2 + 3x $

Before we proceed with evaluating the function $ h(x+a) $, let's first understand the given function $ h(x) = 5x^2 + 3x $. This is a quadratic function, which means it has a parabolic shape. The general form of a quadratic function is $ ax^2 + bx + c $, where $ a $, $ b $, and $ c $ are constants.

In this case, the function $ h(x) = 5x^2 + 3x $ has a leading coefficient of $ 5 $, which means the parabola opens upwards. The coefficient of the linear term is $ 3 $, which indicates the direction of the parabola's opening. The function has no constant term, which means the parabola intersects the y-axis at the origin.

Evaluating the Function $ h(x+a) $

To evaluate the function $ h(x+a) $, we need to substitute $ x+a $ into the given function $ h(x) = 5x^2 + 3x $. This means we will replace every instance of $ x $ with $ x+a $.

Step 1: Substitute $ x+a $ into the function

$ h(x+a) = 5(x+a)^2 + 3(x+a) $

Step 2: Expand the squared term

$ (x+a)^2 = x^2 + 2ax + a^2 $

Step 3: Substitute the expanded squared term into the function

$ h(x+a) = 5(x^2 + 2ax + a^2) + 3(x+a) $

Step 4: Distribute the coefficients

$ h(x+a) = 5x^2 + 10ax + 5a^2 + 3x + 3a $

Step 5: Combine like terms

$ h(x+a) = 5x^2 + (10a + 3)x + 5a^2 + 3a $

Conclusion

In conclusion, the function $ h(x+a) $ for the given function $ h(x) = 5x^2 + 3x $ is $ h(x+a) = 5x^2 + (10a + 3)x + 5a^2 + 3a $. This is a quadratic function with a leading coefficient of $ 5 $, a coefficient of the linear term of $ 10a + 3 $, and a constant term of $ 5a^2 + 3a $. The graph of this function will be a parabola that opens upwards and is shifted to the left or right by the value of $ a $.

Introduction

In our previous article, we evaluated the function $ h(x+a) $ for the given function $ h(x) = 5x^2 + 3x $. In this article, we will answer some frequently asked questions related to function transformation and the evaluation of $ h(x+a) $.

Q1: What is function transformation?

A1: Function transformation is a process of changing the graph of a function by shifting, scaling, or reflecting it. This can be done by adding or subtracting a constant value to the input of the function, multiplying the input by a constant value, or reflecting the graph across the x-axis or y-axis.

Q2: What is the difference between $ h(x) $ and $ h(x+a) $?

A2: The function $ h(x) $ is the original function, while $ h(x+a) $ is the function obtained by shifting the graph of $ h(x) $ to the left or right by a certain value $ a $. This means that the value of $ x $ is replaced by $ x+a $ in the function $ h(x) $.

Q3: How do I evaluate $ h(x+a) $ for a given function $ h(x) $?

A3: To evaluate $ h(x+a) $, you need to substitute $ x+a $ into the given function $ h(x) $. This means replacing every instance of $ x $ with $ x+a $ in the function $ h(x) $. Then, you need to expand and simplify the resulting expression.

Q4: What is the significance of the constant $ a $ in the function $ h(x+a) $?

A4: The constant $ a $ in the function $ h(x+a) $ represents the amount of horizontal shift of the graph of the original function $ h(x) $. If $ a $ is positive, the graph of $ h(x) $ is shifted to the right by $ a $ units. If $ a $ is negative, the graph of $ h(x) $ is shifted to the left by $ |a| $ units.

Q5: Can I use function transformation to solve optimization problems?

A5: Yes, function transformation can be used to solve optimization problems. By shifting, scaling, or reflecting the graph of a function, you can identify the maximum or minimum value of the function.

Q6: How do I use function transformation to analyze data?

A6: Function transformation can be used to analyze data by identifying patterns and trends in the data. By shifting, scaling, or reflecting the graph of a function, you can identify the underlying structure of the data.
