Question

7)

What is the effect on the graph of the function f(x) = lxl when f(x) is changed to f(x) + 5?
A)
shifts up by 5 units
B)
shifts left by 5 units
C)
shifts down by 5 units
D)
shifts right by 5 units

Answer 1

C

Explanation:

f(x) = |x|: f(0) = 0, f(1) = 1, f(-1) = 1

f(x) + 5 = |x| --> f(x) = |x| - 5: f(0) = -5, f(1) = -4 f(-1) = -4

Therefore it shifts down by 5
