100
Find the interval where f(x) is concave up. Justify your answer.
f(x) is concave up on (1, 4) because the average rates of change are increasing.
100
What is the degree of the following function?
6x^7+3x^8-2x^2
8
100
On what open intervals is k(x) both increasing and concave down? 
(-6,-3)
200
Where does f(x) have an inflection point? Justify your answer.
f(x) has an inflection point at x = 1 because the average rates of change change from decreasing to increasing at x = 1.

Use the limit definition to state the end behavior of the polynomial functions.
f(X)= -8x^7+3x^2+5

Calculate the average rate of change of the function 𝑓(𝑥) =
x^2-9x
in the interval 2 ≤ 𝑥 ≤ 7.
0
300
The table gives values of a function f for selected values of x. Is the function linear or quadratic? Justify your choice?
f(x) is quadratic; f(x) has a constant second difference over equal-length input value intervals OR the rates of change are changing at a constant rate.
300
Where is the relative maximum of the function? (Calc. okay)
h(x)=2x^3-4x
(-0.816, 2.177)

a = -12
b = 4
c = 8

f(x)=x^2-4
The average rate of change of over the interval [c, 5] is equal to 3, where c is a constant. Find the value of c.
c = -2

Given the zero 4 − 𝑖, find all other zeros of the polynomial function
f(x)=x^4-8x^3+16x^2+8x-17
−1, 1, 4 − 𝑖, 4 + i
500
Let p(x) be the function that results from applying three transformations to the graph of g in the order: a horizontal dilation by a factor of 1/2, a reflection over the y-axis, and a vertical translation by 1 unit.
Find the average rate of change of p over the interval [-1/2, 4].
g(x)=x^2-2
2/3
