for the columns where is less than or equal zero, use the first line of the function to calculate the value of f(x)

for every x greater than zero, use the second line to determine the value

hope this helps and gives some insight what to do.
if there are open questions left, feel free to ask them in the comments
have a beautiful day

(13/4)*3 = 39/4 ft
I believe that's the answer
<span>you have to create variables that have the same coefficient</span>
Range should be (-∞ , 10]
answer is C.
we conclude that the graphed equation is:
y = 4*cos(pi*x)

Which trigonometric equation is the one in the graph?</h3>
First, we can see that the graphed function is even, so we know that it wiill be a cosine.
We also can see that the maximum is 4 and the minimum is -4, so the amplitude is 4.
Then we have something like:
y = 4*cos(b*x)
To find the value of b, we can use the fact that the zeros of the function are at x = ±1/2
Then:
b*1/2 = pi/2
b = pi
Finally, we conclude that the graphed equation is:
y = 4*cos(pi*x)
