Question

I rly need some help quick:)) Can someone solve these 2 short equations?
f(2) when f(x) = 3x + 2
f−1(3) when f(x) = 2x-7/3

Answer 1

3(2)+2=

6+2=8

the first equation =8

(to find X in the second equation, multiply -1 and 3... you get -3)

2(-3)-7/3=

-6-7/3= -25/3

the second equation = -25/3 or -8 1/3
