Here is a graph I hope it clears it up
Hi, I'm just going through a practice exam and looking over my answers compared to the answer key.
It asked for the range of the function in interval notation.
I put down [-1, 2], because I figured the amplitude was 3?
But the answer is [-4, 2]
I need some clarification as to why. Am I missing something? Do I multiply the amplitude by 2 or something weird?
Thanks in advanced.
