Answer:
(c) output increases, then decreases ...
Step-by-step explanation:
The given function is quadratic, so it has a turning point. Neither linear nor exponential functions have a turning point, so are always increasing or decreasing.*
The second attachment shows a plot of the function with input on the x-axis and output (area of the rectangle) on the y-axis.
_____
* A linear function that is a horizontal line will be neither increasing nor decreasing.
Answer:
1. 2/8 = 12/48
2. 18/20 = 99/110
Step-by-step explanation:
If you divide 2 by 8, you get .25. Knowing this, you can just expand it into another form. 12/48 (simplified into 2/8, aka 1/4) would also be .25 if divided. If you divide 18 by 20, you get .9, and same with if you divide 99/110.
Hope this helped! :)

Answer:
Correct rate of change is -5; correct initial value is 3.
Step-by-step explanation:
The rate of change is the coefficient of the x term, which here is -5. So Bryan has the rate of change wrong.
The initial value of the function is found by letting x = 0. Here, we get
y = -5(0) + 3, or y = b = 3. The initial value is 3, not -5.
