Question

What are all the real zeroes fo y=(x-12)^3-7?

Answer 1

Real zeros means the roots o the equation.

Roots of the equation can be found by making y=0 and solving the equation

So when y=0

 0=(x-12)^3-7
 X^3+36x^2+432x-1735=0

Roots of the equation can't be found algebraically so by numerically X=13.912931
