Aradio is being discounted 20%. if the sale price of the radio is $17.76, what was the original price of the radio?

A discount of 20% means the price is going to be 100% - 20% of the original price, so it'll be 80%.

x * 0.80 = $17.76

x = $22.20

(- 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 )
