g (x) = f (x + 1) - 2

g (x) = (x + 1 + 3) ^3 - 2

g (x) = (x + 4) ^3 - 2

Now what are we supposed to do with this? I'm guessing we are to find what value of x will make g (x) = 12. If I'm wrong, leave a note in the form of a comment.

g (x) = 12

(x + 4) ^3 - 2 = 12 Add 2 to both sides.

(x + 4) ^3 = 14 Take the cube root of both sides.

x + 4 = cubrt (14)

x + 4 = 2.4101 Subtract 4

x = 2.4101 - 4

x = - 1.5899

If f (x) = (x+3) ³+4

let g (x) = f (x+1) - 2

find when g (x) = 12
