(- 1, 0 )
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 )
answer: it is 8
you know why its 8
so the equation for this is:
ab being the top length of 6 and ac being the length of 2 and ad being the length of x. let's plug into the equation:
6^2 = 2x
now lets just solve for x:
36 = 2x
18 = x
i hope that !
