Transformations

Rules

Example

If the parent function is f(x) = x2, how does the graph of the function

f(x) = (x - 3)2 + 4 compare?

Step 1. How does the graph move right or left?

The number inside the parentheses is -3, therefore the graph moves right 3.

Step 2. How does the graph move up or down?

The number outside the parentheses is + 4, therefore the graph moves up 4.

Step 3. What does the new graph look like?
