Question

Evaluate the function.f(x) = -3x^2 - 6Find f(-9)

Answer 1

Given the function

`f(x)=-3x^2-6`

You have to find f(-9), to do so you have to replace the equation with x=-9 and calculate the value of f(x)

`\begin{gathered} f(x)=-3x^2-6 \\ f(-9)=-3(-9)^2-6 \\ f(-9)=-3(81)-6 \\ f(-9)=237 \end{gathered}`

When x=-9, the function has a value of 237
