13 A local business is calculating the total profit made f(x) after selling
x cupcakes. The business would like to predict their profit by creating an equation for the function.

Write an equation that models the total profit for the business below.
Drag and drop the numbers into the boxes to create the function's equation. Not all numbers listed will be used.

x | f(x)
_
3 | -5
7 | -2
11 | 1
15 |4
(it won’t allow me to send another pic with the chart so i hope this helps. & the picture i did attach are the things you have to use to create the problem it has to be in the form f(x) = _ x + _

The required equation is:

Step-by-step explanation:

We need to find equation from the table given

x     f(x)

3     -5

7     -2

11     1

15    4

We can write equation in the form of

where m is slope and b is y-intercept.

Finding Slope

We can used the slope formula to find slope:

From the table we have:

Putting values and finding slope

So, we get slope

Now, finding y-intercept

Using the slope and point (3,-5) we can find y-intercept

The y-intercept is

So, the equation having slope and y-intercept will be:

The required equation is:

the answer is $42.96
