The function f(x)=18000(0.52)x represents the value in dollars of a vehicle x years after it has been purchased new. what is the average rate of change in value per year between years 4 and 8?

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

idk idk idk idk idk

step-by-step explanation:

you can use a^2+ b^2=c^2
