Note that your function can be written as

So, if x is negative, your function is identically equal to 1. In particular, the limit as x approaches -2 will be 1 as well.
We can model this situation with a linear equation. We know for our problem that the initial point is (0, 25), and the next point is (10, 108.4). To relate those points and find the slope of our linear equation, we are going to use the formula:

. Notice that we know from our points that:

,

,

, and

. So, lets replace those values in our formula to find

:



Now that we have the slope of our linear equation, we can use the point slope formula:

to complete our linear equation:



Or in function notation:

We can conclude that the equation that matches this situation is

.

- Please prefer the picture for your answer.
- We know, area of a ∆ = 1/2 × base × height.
- Here, base = ( 7 + 1) units = 8 units.
- Height = (7 - 1) units = 6 units.
- Therefore, the area of the ∆
- = (1/2 × 8 × 6) square units
- = 24 square units.
