A. consider f: r-> r given by f(x)-7x+11. explain why we know that this function does have an inverse. b. for f : r-r given by f (x)-7x+11, find the inverse, f (x)

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=
