Question

What are the x-intercepts of this quadratic function? g(x) = -2(x − 4)(x + 1)

Answer 1

(4,0) and (-1,0)

Explanation:

Answer 2

For this case we must find the x-intercepsts of the following function:

`g (x) = - 2 (x-4) (x + 1)`

For this we do
`y = 0`, that is:
`g (x) = 0`. So:

`0 = -2 (x-4) (x + 1)`

The values of "x" that comply with equality are:

`x_ {1} = 4\\x_ {2} = - 1`

Thus, the x-intercepsts of the function are:

`(x_ {1}, y_ {1}) :( 4,0)\\(x_ {2}, y_ {2}): (- 1,0)`

Answer:

`(x_ {1}, y_ {1}) :( 4,0)\\(x_ {2}, y_ {2}): (- 1,0)`
