Question

Find the zeros of the function.

Enter the solutions from least to greatest.

f(x) = 5x^2 - 20

lesser x =

greater x =

Answer 1

lesser x = -2

greater x = 2

Explanation:

The values of a function f(x) are the values of x for which f(x) = 0.

In this question:

`f(x) = 5x^2 - 20`

So, finding the zeros:

`5x^2 - 20 = 0`

`5x^2 = 20`

`x^2 = (20)/(5)`

`x^2 = 4`

`x = \pm √(4)`

`x = \pm 2`

So

lesser x = -2

greater x = 2
