For this case we have the following functions:

We must find the following sum of functions:
(f + g) (x)
By definition we have to:

So, we have to:

Answer:

Using linear function concepts, it is found that:
a) The initial value is of 3 and the rate of change is of 20.
b) The rate of change means that for <u>each hour, the cost increases by 3 Dhs</u>, while the initial value means that <u>a flat fee of 20 Dhs is paid</u>.
<h3>What is a linear function?</h3>
A linear function is modeled by:

In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and also can be considered as the initial value.
In this problem, the function that gives the charge C for renting a bicycle for h hours is:

Item a:
Comparing to the standard function, we have that:
- The initial value is of 3 and the rate of change is of 20.
Item b:
The rate of change means that for <u>each hour, the cost increases by 3 Dhs</u>, while the initial value means that <u>a flat fee of 20 Dhs is paid</u>.

Answer:
38 Students love math the most
Step-by-step explanation:
<u>Step 1: Find how much math is left</u>
Total: 90
Already said: 32 + 20 -> 52
Total - Already said = Math
90 - 52 = 38
Answer: 38 Students love math the most
The answer would be (3,1)
