Idont need any work just the answer for both worth 300 points

1) For any one input there is only one output,

So because there are 2 x's with 4 and they both have different outputs ( y values are different) it cannot be a function.

The answer is D.

2) There are two x's using -3 and each Y value is different, one is 2 and the other is 0, so it is not a function.

The answer is D.

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
