Your internet service provider (ISP) charges a $55 installation fee and a fixed charge per month for its service. The total cost for monthly service after 6 months is $455. Write an equation for cost, C, after t months of service. Question 2 options:

C=55.83t+55

C=65t+55

C=55t+455

C=55t+65

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)

1) letter c.

2) 4 square root of 9
