Answer:
y = 7 csc ( x /2) - 2
Step-by-step explanation:
The parent csc x function has the range ( - ∞, -1] U [1,∞ ) infinity, meaning its "width" is 2. Now our function has range ( - ∞, -9] U [5,∞ ), with a width of 5 - (-9) = 14, which is two times as much as that of the parent function function. This tells us that the function is vertically stretched by a factor of 14 / 2 = 7, and so we have
Now, the parent function csc x has vertical asympototes at x = 0 and x = π. Our function, however, has consecutive asymptotes at x = 0 and x = 2 π. Meaning our functin is streched horizontally by a factor of 2. Therefore, we do x --> x / 2 and so we have
Lastly, we observe that the function is not symmetric about the x-axis, whereas the parent function is. This tells us that some vertical shifting is involved. How much vertical shifting exactly?
We find the answer by finding the midpoint
which is the vertical shift.
Therefore, the final form of our function is
which is our answer!
