Math Problem Statement

Use transformations of f(x) = x^2 to graph the following function. h(x) = (x + 2)^2 + 5

Solution

The question asks for the transformations needed to graph the function h(x)=(x+2)2+5h(x) = (x + 2)^2 + 5 using the basic quadratic function f(x)=x2f(x) = x^2 as a starting point.

We can break this down into two transformations:

  1. Horizontal Shift: The term (x+2)2(x + 2)^2 represents a shift 2 units to the left. This is because adding 22 inside the parentheses moves the graph in the negative xx-direction.

  2. Vertical Shift: The +5+5 outside the squared term represents a shift 5 units up. This shifts the graph upward by 5 units on the yy-axis.

So, the required transformations are:

  • A horizontal shift 2 units to the left.
  • A vertical shift 5 units up.

Here are 5 related questions for you to consider:

  1. What happens to the graph if the constant inside the parentheses is negative, like h(x)=(x3)2+5h(x) = (x - 3)^2 + 5?
  2. How would the graph change if the +5+5 were replaced with a negative value, like h(x)=(x+2)23h(x) = (x + 2)^2 - 3?
  3. How do horizontal and vertical stretches or compressions affect the transformation of f(x)=x2f(x) = x^2?
  4. Can you describe how to graph h(x)=(x+2)2+5h(x) = -(x+2)^2 + 5 based on the transformations?
  5. How would you graph h(x)=2(x+2)2+5h(x) = 2(x+2)^2 + 5, where the quadratic term is multiplied by a coefficient?

Tip: When applying transformations, always follow the order: horizontal transformations, then vertical transformations.
