A treadmill is set to have intervals of mild incline of 5 degrees and steeper incline of 15 degrees during a workout. The function W gives the incline of the treadmill W(x) , in degrees, 2 minutes after the workout begins.
On challenge days, the incline settings are 5 degrees steeper to increase the difficulty. The function C gives the incline of the treadmill C(x). in degrees, I minutes after the workout begins on challenge days.
a. If W(20)=5 , then what is the corresponding point on C? Use function notation to describe the point on C. Type the answer in the box below. The corresponding point on C would be C(20)=10
b. If W(30)=15 , then what is the corresponding point on C? Use function notation to describe the point on C. Type the answer in the box below. The corresponding point on C would be C(30)=20
c. Write an expression for C' in terms of W Type the answer in the box below.
