ANSWER

EXPLANATION
The given function is a piecewise defined function.

is the y-value that corresponds to

To determine that y-value, we need to trace from

to where it meets the graph.
We then trace to the y-axis to determine the corresponding y-value as shown in the diagram.
From the graph, we can see that this x-value corresponds to a y-value of

This implies that, when

Therefore

See graph.
Answer:
10 square units
Step-by-step explanation:
We want to find the area under the curve
from x=1 to x=3.
We use definite integrals to find this area.

We integrate to obtain:

We evaluate the limits to get:


Therefore the area under the curve from x=1 to x=3 is 10 square unit.
Answer:
a) The equation is y = 6x + 25 since the 25 is the initial fee.
b) We plug in 10 for x. 6 * 10 + 25 = $85.
c) We plug in 7 for x and get 6 * 7 + 25 = $69.
