Step-by-step explanation:
Consider the provided information.
Sandy charges each family that she babysits a flat fee of $10 for the night and an extra $5 per child.
Let x is the number of child, Sandy charges fixed fee of $10 and $5 for each child. Thus, the charges for one night is:
Kimmi charges $25 per night no matter how many children a family has. Thus, the charges for one night is:
Now we need to write an equation that would compare the two girls charges:
Thus, the required equation is .
Now we need to find how many children a family have in order to be the same charges.
For the same charges solve the equation as shown:
So, the number of children has to be 3 for same charge.

For this case we have that the main function is given by:
We apply the following transformations:
Vertical expansions:
To graph y = a * f (x)
If a> 1, the graph of y = f (x) is expanded vertically by a factor a.
For a = 5 we have:
Vertical translations:
Suppose that k> 0
To graph y = f (x) + k, move the graph of k units up.
For k = 5 we have:
Answer:
The graph of g (x) is the graph of f (x) stretched vertically by a factor of 5 and translated up 5 units.
