Question

find the inverse of f(x)=2x-3
a. y=(x+3)/2
b.y=-4x-12
c. y= 2x-3

Answer 1

y=2x-3
to get the inverse switch x&y
x=2y-3
y=(x+3)/2

Answer 2

Or one simple way to check is that the inverse function is suppose to have an inverse slope... a is the only one that has an inverse slope so that's the answer
