Question

Find the inverse of f(x)=-3x+3

Answer 1

to get the inverse, first off do a quick switch on the variables, and then solve for "y".


`\bf f(x)=y=-3x+3\qquad \qquad inverse\implies \boxed{x}=-3\boxed{y}+3 \\\\\\ x-3=-3y\implies \cfrac{x-3}{-3}=y\implies \cfrac{3-x}{3}=y\impliedby f^(-1)(x)`
