Math Problem Statement

Alicia graphed the function h(x) = (x - 7) + 5. What is the effect on the graph of the parent function f(x) = x? Select TWO correct answers.

Solution

Let's analyze the function h(x)=(x7)+5h(x) = (x - 7) + 5 in relation to the parent function f(x)=xf(x) = x.

  • The expression (x7)(x - 7) indicates a horizontal translation of 7 units to the right. This is because subtracting a value inside the function moves the graph to the right.

  • The +5+5 added outside the function indicates a vertical translation of 5 units up. Adding a number to the function shifts the graph upwards.

Thus, the two correct answers are:

  • A. The graph of ff is translated 7 units right.
  • D. The graph of ff is translated 5 units up.
