<u>Given</u>:
The given function
which models the value of Mark’s car, where x represents the number of years since he purchased the car.
We need to determine the approximate value of Mark's car after 7 years.
<u>Value of the car:</u>
The value of the car after 7 years can be determined by substituting x = 7 in the function
, we get;



Rounding off to the nearest dollar, we get;

Thus, the approximate value of Mark's car after 7 years is $14278.
Hence, Option a is the correct answer.
Answer: The slope is 
Step-by-step explanation:
The slope of a line can be calculated with the following formula:

Observe the graph provided in the exercise.
You can notice that these two points are on the line:
and 
Then you can identify that:

Knowing these coordinates, you can substitute values into the formula for calculate the slope.
Then, you get that the slope of the graph is:

Answer:
The correct answer is
A.) Chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card
Step-by-step explanation:
On edge :)
(x) basically means y, and f'(x) means dy/dx. The x can have a value, so for example, f(x) = 2x + 1, then f(1) = 3.
