Question

Plese help i need the answer

Answer 1

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 each hour, the cost increases by 3 Dhs, while the initial value means that a flat fee of 20 Dhs is paid.

What is a linear function?

A linear function is modeled by:

$y = mx + b$

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:

$C(h) = 3h + 20$

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 each hour, the cost increases by 3 Dhs, while the initial value means that a flat fee of 20 Dhs is paid.
