Y+6=15 and (y+6) / 3=15 equivalent expressions

No.

When you simplify (y+6)/3=15, you get y/3+2=15, which is not the same as y+6=15.

(- 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 )
