Question

Algebra 2 how do I do this?

Answer 1

im in 9th grade algerbra 1 and i just learned this a week and a half ago so ill help

Explanation:

x=7 so----

f(x)=3x so you substitute the (x) with (7)

f^-1 (x) witch would be f^-1 (7) cause you still put the (7) cause you use it to substitute the (x)

witch that would equal 7 over F

if that helps
