Question

What are the domain and range of the function?

Answer 1

Answer:

$x$ = - 2/7

Alternate form: - 0.285714

Step-by-step explanation:

1- Substitute f ( x ) = 0

Reorder

f ( $x$ ) = $x$ x 2 - 16$x$ - 4

2- Collect like terms

0 = 2$x$ - 16$x$ - 4

3- Move the variable to the left

0 = - 14$x$ - 4

4- Divide both sides

14$x$ = - 4
