John o'sullivan has just completed his first year in business. his records show that he spent the following in advertising:

internet $620 radio $610 yellow pages $750 local flyers $420

what percent of john's advertising was spent on the yellow pages?

(- 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 )

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
