Question

how do you find the zeros of a function

Answer 1

Factoring or using the quadratic equation.

The zeros are the points where equation becomes zero.

For example, for f(x)=x^2-1, the zeros would be 1 and -1.

x^2-1=(x+1)(x-1), so if the entire equation becomes zero, one of the two resulting numbers must be zero, therefore x+1=0 or x-1=0.
Solve for those two and you have x=1 and x=-1. And there you have it.

Answer 2

how would you solve f(x)=3x^4-14x^2-4x

Answer 3

Replace f(x) with 0 then solve

Answer 4

ok i think i get it
