EXPLANATION
The period refers to the interval over which the function completes one full cycle.
The given function completed four cycles in on the the interval.
[-π,π]
The period is
Simplify;
The last choice is correct.
Answer:
$100
Step-by-step explanation:
We can see from the graph that the rate of change is $20. This is because for every increase in x, the value of y increases by $20.
Going from this, the value at x=4 is $80; this will make the value at x=5
80+20 = 100

Are there any answer choice
Answer:
y = -1/3x + 5
Step-by-step explanation:
To solve this, we use the equation y = mx + b
Where m is our slope and b is our y intercept
Since the line intersects at 5, our b value will be 5
Now to solve for m, we count how many times we go down and across to reach a new point.
So we start at (0,5), then we go to (3,4)
We can subtract 4-5 to get -1, then divide that by 3-0 which is 3
So you will get m = -1/3
Hope this helps
