Question

What domain and range are responsible for the function?

Answer 1

Answer:

Domain { 0 ≤ r≤ 18}

Range = {0≤ c ≤ 31.5}

Step-by-step explanation:

The domain is the values that r can take

He can goes on each ride up to 1 time

R can be from 0 rides to 18 rides since there are only 18 rides

Domain { 0 ≤ r≤ 18}

The range is the output

If r = 0 then he spends no money

if r =18 then 1.75*18 =31.5

Range = {0≤ C(r) ≤ 31.5}
