At Sandy's Beauty Salon, a haircut costs $15.00 and a permanent costs $30.00. Which graph represents the amount of revenue the salon will earn in one day for x haircuts?

y=15x

Step-by-step explanation:

revenue=cost of hair cut(number of haircuts)

answer: this doesnt make any sense especially the photo.

step-by-step explanation:

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option
