Answer:

Step-by-step explanation:

Here the "common ratio" is 0.70.  At the end of the first year the car will be worth 0.70 times its original value; let's call that w1.  At the end of the second year the value will be 0.70*w1.  And so on.  The value continues to drop year by year, nearing but not equalling zero.

This type of function is a "decaying exponential."

Next time please share the answer choices.  Thank you.

Which table does NOT represent a linear function
topjm [15]

TABLE D does NOT represent a linear function

<h2>Explanation:</h2>

The Table is shown below. Each table is a relationship between two variables, namely x and y. By plotting each table in a graphing tool we get:

TABLE A, FIRST FIGURE:

It is a linear function because we can draw a line that passes through all the points. By using two points, this line has a slope:

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\ \\ m=\frac{8-5}{-1-0} \\ \\ m=-3

TABLE C, SECOND FIGURE:

It is a linear function because we can draw a line that passes through all the points. By using two points, this line has a slope:

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\ \\ m=\frac{5-10}{-1-0} \\ \\ m=5

TABLE C, THIRD FIGURE:

It is a linear function because we can draw a line that passes through all the points. By using two points, this line has a slope:

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\ \\ m=\frac{1-2}{-1-0} \\ \\ m=2

TABLE D, FOURTH FIGURE:

It is not a linear function. It is likely this is a parabola that opens downward.

Hi.
This is just messing around with exterior angles.
I say around 120 degrees, if I forgot what exterior angles were.
But <em>with quick calculation, it is probably 120 degrees</em>

The function f(x) = –x2 − 2x + 15 is shown on the graph. What are the domain and range of the function?
Phantasy [73]

Find the domain by finding where the function is defined. The range is the set of values that correspond with the domain.

Domain: ( − ∞ , ∞ ) , { x | x ∈ R }

Range: ( − ∞ , 16 ] , { y | y ≤ 16 }
