For a: a+r=t solve for the indicated variable

a+r=t

move +r to the other side

sign changes from +r to -r

a+r-r=t-r

a=t-r

(- 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 )
