Question

I don’t know how to do this problem in math

Answer 1

142

Explanation:

Basically, in f (x) whatever x is will go in the parenthesis.

So,

`-(-9)^(2)`
`-7(-9)-2`

The two negatives that are next together will turn positive.

`9^(2)`
`+63`
`-2`

When multiplying two negative numbers turn positive.

9 x 9= 81

81+63-2

144-2=142
