Question

(Look at screenshot)

7. The graph represents the height of a passenger car on a ferris wheel, in feet, as a
function of time, in seconds.
Use the graph to help you:

a. Find H(0).
b. Does H(t)=0 have a solution? Explain how you know.
c. Describe the domain of the function.
d. Describe the range of the function.

Answer 1

#a

H(0)

It refers to y value on graph when x is 0

So here it refers to y intercept

• y intercept (0,5)

Hence

• H(0)=5

#b

Observe the graph

y intercept is not 0 so it's not true

#3

Domain is set of x values in graph

• [0,oo)

#4

Range is set of y values on graph

• [5,50]
