Question

Find the zeros of the function f(x)=x^2-2x-3 to the nearest hundredth.

Answer 1

x=3, x=-1

Explanation:

Finding zeros of a function means plugging in 0 for f(x).

You'll get 0=x^2-2x-3.

Then solve by plugging in equation into quadratic formula: -b±√b^2-4ac/2a

Simplify and you'll get x=3, x=-1.

Hope this helped.
