THIS IS THE LAST QUESTION FOR MY HW PLEASE I JUST WANT TO GO TO SLEEP For f(x) = -6x + 7, determine f^-1 x 4
the 4 is not a part of the power ^1!!!

Explanation:

In order to have an inverse function, a function must be one to one.

In the case of

f

(

x

)

=

x

4

we find that

f

(

1

)

=

f

(

−

1

)

=

1

. So

f

(

x

)

is not one to one on its implicit domain

R

.

If we restrict the domain of

f

(

x

)

to

[

0

,

∞

)

then it does have an inverse function, namely:

f

−

1

(

y

)

=

4

√

y

$12. that is my answer.
