Can some one explain how to do this or where i can find

Ok, so what they are asking is that you plug in numbers for the given equation and see if it matches. When it says "Find another set of values", just find another pair that will make it work.

(- 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 )
