Answer:

f(8) = -161

Explanation:

The question is asking us to evaluate the function.

In this problem, the function is:


\large{\textsf{$ f(x) = -3x^2 + 3x + 7 $}

Plug in 8 for x:


\large\text{$ f(8) = -3(8)^2 + 3(8) + 7 $}

Simplify.


\large\text{$ f(8) = -3 * 64 + 24 + 7 $}


\large\text{$f(8) = -192 + 31 $}


\large\text{ f(8) = -161}

Therefore, f(8) = -161.

Answer:

f(8)=-161

Explanation:

f(x) = -3x^2 + 3x + 7

f(x) = -3x2 + 3x + 7

f(8)= -3(8)^(2) + 3(8) + 7= -192+24+7=-161
