Question

SOMEONE PLEASE CHECK MY ANSWER? WILL GIVE AN MEDAL FOR SURE! :)
The defining equation of the machine f which takes a number, cubes it, then subracts 17 from the result is

f(x) = 3x - 17
f(x) = x^2 - 17
f(x) = x^3 - 17
f(x) = x^3 - 17^3

Answer 1

i said f(x)=x^3-17
am i right or wrong?

Answer 2

got it

Answer 3

yep you are right its the third answer!!
