Question 9 • Precalculus

The function h(x) = –x5 + 12x is an odd function. Which transformation of h(x) results in an odd function?

Answer
A
h(5 – x)
B
1 + h(x)
C
h(x + 8)
D
–6h(x)

Explanation

Multiplying an odd function by a constant preserves oddness. For g(x) = −6h(x), g(−x) = −6h(−x) = −6(−h(x)) = 6h(x) = −g(x), which is the defining rule for an odd function. So the transformation −6h(x) results in an odd function.
