Answer: Period: 4. Amplitude: 3
Step-by-step explanation: The period is how long it takes for one cycle of the function (one up and down). In this graph, one cycle ends at 4.
The amplitude is how far away the extremes of the graph are from the midline. This graph is a total of 6 units tall, making the amplitude 3. (I usually find total graph height and divide by 2.)
So, this is what it looks like
8+9x+4(11-2x)
You deal with the 4(11-2x) first.
44-8x
Combine like terms
44+8=52
9x-8x= x
The slope is negative one
