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 =
Change y back into terms of x, then
(x) =
=
→ A
So since its a right triangle, we can use the pythagorean theorem, which is . Since we know that 2 and 3 are our legs and x is our hypotenuse, we can solve the equation as such:
Since √13 can't be further simplified, that is your final answer.
