Question

What equation is generated if f(x) = x is moved to the right 5 units and then down 8 units?

A.) f(x) = (x – 5) – 8
B.) f(x) = (x – 8) + 5
C.) f(x) = (x – 8) – 5
D.) f(x) = (x + 5) – 8

Answer 1

Answer:  A)  f(x) = (x-5)-8

Explanation:

To shift 5 units to the right, we replace x with x-5. This moves the xy axis 5 units to the left to give the illusion the function curve moves 5 units to the right. The -8 at the end shifts the curve down 8 units.
