Question

For the function f(x) = (3 – 4x)², find f–1. Determine whether f–1 is a function. show work. help. medal rewaarded!

Answer 1

f(-1) ? or (f-1) Which do you mean

Answer 2

its f^-1

Answer 3

f(x)^-1?

Answer 4

If so then it would just be f(x)^-1=(3-4x)

because the exponents when multiplying are added. 2+(-1)=1

Unless I have interpreted what the question is asking for wrongly.

Answer 5

No... Switch x and y then solve for y.

y = (3 – 4x)²
x = (3-4y)^2

Solve for y

Answer 6

Oh right that means inverse lol. Yes, make sure it's inversable as a one to one function, switch x and y like ^^^^said and solve for y.

Answer 7

im stumped!:(

Answer 8

x = (3-4y)^2

y= 1/4 (3-sqrt(x))

so... f^-1 = 1/4 (3-sqrt(x))
