Question

Please solve. Evaluate the function.

Answer 1

Answer:

(g o f)(x) = $\sqrt{-510}$ (not simplified)

Step-by-step explanation:

(g o f)(x) = g(f(x))

g(x) = $\sqrt{3x}$  f(x) = $x^{3} + 9x$

g(f(-5)) = g($(-5)^{3} + 9(-5)$ = $(-125) + (-45)$ = $-170$

g(-170) = $\sqrt{3(-170)}$ = $\sqrt{-510}$
