Answer:
Choice A: x^2−2x+4− 15/x+2
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y =
( multiply both sides by x³ )
x³y = 19 ( divide both sides by y )
x³ =
( take the cube root of both sides )
x = ![\sqrt[3]{\frac{19}{y} }](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%5Cfrac%7B19%7D%7By%7D%20%7D)
Change y back into terms of x, then
(x) =
=
→ A
False because to find a reciprocal u gotta divide that number by one (example: 1 divided by 8 is 1/8) there you go , so therefore the answer is false. :)
