Question

13. Which equation defines the graph of y = x^2 after it is shifted vertically 3 units up and horizontally 2 units right?

Answer 1

The three units upward shift is denoted by +3 outside of the parenthesis and horizontal shift to the right is represented by -2 inside the parenthesis.
The answer is C.

Answer 2

     The graph of y = x²  ( the parent function ) is shifted vertically 3 units up and horizontally 2 units right:
y = ( x - h )² + k,  where:  h = 2 and k = 3
Answer:
C )   y = ( x - 2 )² + 3
