Question

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

Answer 1

Answer:

142

Step-by-step 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
