11. Mike is a veterinarian. He is placing a 9-line classified ad for an assistant. The following piecewise function gives the price of an
X-line ad.
45
when <3
45 + 9x - 3) when x > 3
a. Find the difference between the cost of a 2-line ad and the cost of
a 3-line ad
b. Find the cost of a 10-line ad.
6. Find the cost of an 11-line ad.
d. Can you find the difference between the cost of a 15-line ad
and a 17.line ad, without finding out the cost of each ad first?
Explain

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)  

you a real one for tat answer
