Question

A dog groomer charges her clients by the weight of the dog. The following piecewise function represents the total charge, f(𝑥), for a dog weighing x pounds.

f(x)=⎧⎩⎨⎪⎪2.5x if 0≤x≤203.5x if 20 <x≤50 5x if x>50

What would be the last point graphed on the first piece of the function, f(x)=2.5x?

Answer 1

(20, 50)

Because the first piece ends at x = 20, and f(20) = 2.5(20) = 50, so the endpoint is (20, 50).
