Which is the quadric variation equation for the relationship?
y varies directly with x^2 and y=72 when x=6
a. y=2x^2
b. y=4x^2
c. y=12x
d. y=x^2+25

(- 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 )
