Step-by-step explanation:u devide .4 to .56
The value of f( -2) is 24
<em><u>Solution:</u></em>
Given function is:

We have to evaluate the given function for f( - 2)
We can obtain the value of f( -2) , by substituting x equal to -2 in given function
Plug in x = -2 in given function

Solve and simplify the above expression

Thus value of f( -2) is 24
(96+92+80+91+86+x)= 90
________________
6
(445+x)=90
_____
6
then you multiply 6 on both sides
445+×=540
-445. -445
x= 95
they need a 95 percent to have an average of a 90%.
