Functions can be modeled by equations, tables and graphs
From the question, we have the following ordered pairs
(x,y) = (0,1) and (4,2)
The function is a linear function.
So, we start by calculating the slope (m) using:
[tex]m = \frac{y_2 - y_1}{x_2 -x_1}[/tex]
Substitute known values
[tex]m = \frac{2 - 1}{4 - 0}[/tex]
[tex]m = \frac{1}{4}[/tex]
The equation is then calculated as:
[tex]y = m(x -x_1) +y_1[/tex]
This gives
[tex]y = \frac 14(x -0) +1[/tex]
[tex]y = \frac 14x +1[/tex]
The domain of the above function is the set of whole numbers
Substitute 10 for x, to calculate the number of box office gross for week 10
[tex]y = \frac 14 * 10 +1[/tex]
[tex]y = 3.5[/tex]
Approximate
[tex]y = 4[/tex]
Hence, the company should expect 4 box office gross in week 10
