f(x)=4/4x-3 find a formula f^-1(y)

OpenStudy (anonymous):

you need the inverse?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

f(x)=y. so you have y=4/4x-3. to find the inverse substitute the x and y. so now you have: 4/4y-3=x then solve for y

OpenStudy (anonymous):

i got f^-1(x)= 3x+4/4x

OpenStudy (anonymous):
