Question 15 • WSFCS Math 2 CR

Which is one of the transformations applied to the graph of f(x)=x2 to change it into the graph of g(x) = –x2 + 16x – 44?

Answer
A
The graph of f(x) = x2 is widened.
B
The graph of f(x) = x2 is shifted left 8 units.
C
The graph of f(x) = x2 is shifted down 44 units.
D
The graph of f(x) = x2 is reflected over the x-axis.

Explanation

Complete the square: g(x) = −x² + 16x − 44 = −(x − 8)² + 20. The negative sign in front of the squared term means the parabola is reflected over the x-axis; it is also shifted right 8 units and up 20 units. So one transformation is that the graph is reflected over the x-axis.
