Answer:

Step-by-step explanation:



Answer: To graph the sine function, we mark the angle along the horizontal x axis, and for each angle, we put the sine of that angle on the vertical y-axis. The result, as seen above, is a smooth curve that varies from +1 to -1. Curves that follow this shape are called 'sinusoidal' after the name of the sine function.

Answers:
Input 0 = Output 25
Input 1 = Output 23
Input 4 = Output 17
Input 7 = Output 11
Equations:
25 = 25 - (2*0)
23 = 25 - (2*1)
17 = 25 - (2*4)
11 = 25 - (2*7)
Don’t know if this is right or not, if it isn’t sorry!
Answer:
-6
Step-by-step explanation:
The average rate of a function f(x) on the interval from x=a to x=b is
.
So in the problem you have from
to
.
The average rate of the function from x=2 to x=4 is
.
Now we need to find f(4) and f(2).
f(4) means what is the y-coordinate that corresponds to x=4 on the curve.
f(4)=-15 since the ordered pair at x=4 is (4,-15).
f(2) means what is the y-coordinate that corresponds to x=2 on the curve.
f(2)=-3 since the ordered pair at x=2 is (2,-3).
So let's plug in those values:
.
Now we just simplify:
