Question

Find the inverse of the function.
f(x)=3squareroot x/8-4

i keep getting f−1(x)=512x3+6144x2+24576x+32768

Answer 1

when these are the answer choices f-1(x) = [8(x + 4)]3
f-1(x) = 8(x + 4)3
f-1(x) = 8(x3 + 4)
f-1(x) = 24(x + 4)

Answer 2

Can you draw the function?

Answer 3

Because it's not very clear. :)

Answer 4

hi... is this your function?
\(\Large f(x)=3 \times \sqrt{ \frac x{8-4}}\)

Answer 5

no

Answer 6

is it this?
\(\Large f(x)=3 \times \sqrt{ \frac x8-4}\)

Answer 7

\[f(x)=\sqrt[3]{x/8}-4\]

Answer 8

Step 1: Change f(x) to y.
Step 2: Flip x and y. So y will become x, and x will become y.
Step 3: Make the function look like this--> y=mx+b
