Step-by-step explanation:
4 1/4x3=12 3/4
-3x+7
Step-by-step explanation:
The entire function f is being multiplied by -1, -1 isn't being plugged in for x in this case.
f -1(x)= -1(3x-7)
f -1(x)= -3x+7
8(6x-7)
Expand it: 8*6 and 8*7 = 48x-56
This is as low as you can simplify without being able to solve for x :)
