Question

h(x) = 3x^2, find h(-5).

Answer 1

Answer:

h(-5) = 75.

Explanation:

Given h(x) defined below:

$h\mleft(x\mright)=3x^2$

To find the value of h(-5), substitute -5 for x in h(x):

$\begin{gathered} h(-5)=3(-5)^2 \\ =3\times25 \\ =75 \\ \implies h(-5)=75 \end{gathered}$

The value of h(-5) is 75.
