Question 3 • AZ-Common Core Algebra II A

Which is one of the transformations applied to the graph of f(x) = x2 to produce the graph of p(x) = –50 + 14x – x2?

Answer
A
a shift down 1 unit
B
a shift left 7 units
C
a shift right 1 unit
D
a shift up 7 units

Explanation

Complete the square: p(x) = −x² + 14x − 50 = −(x − 7)² − 1. The −1 at the end means the graph is shifted down 1 unit, so choice A is correct. The expression also shows a reflection across the x-axis and a shift right 7 units.
