Answer:
142
Step-by-step explanation:
Basically, in f (x) whatever x is will go in the parenthesis.
So,
[tex]-(-9)^{2}[/tex][tex]-7(-9)-2[/tex]
The two negatives that are next together will turn positive.
[tex]9^{2}[/tex][tex]+63[/tex][tex]-2[/tex]
When multiplying two negative numbers turn positive.
9 x 9= 81
81+63-2
144-2=142
