The piecewise function describes a newspaper’s classified ad rates. y = {25 when x≤4
25 + 5 (x − 4) when x > 4

a) Interpret this piecewise function (describe in words what it means) (2 points)

Find the cost of a 3 line ad (2 points)

Find the difference in cost between a one and four line ad (2 points)

Find the cost of a seven line ad (2 points)

o= 4(i) +3

step-by-step explanation:

o is your output value and i is your input value. so, for example, if we stuck 7 in as our input, we would first multiply by 4 ( pemdas ), which equals 28. then we would add 3 to 28, for a total output of 31. this may not be a graph, but, it is a way to solve your formula..
