What is the average rate of change in the interval
[0, 4] ?
f(4) - f(0)
1 - - 1 / 4-0
= 2/4 = 1/2
True or false: {x is any integer | 3 < x < 5} is in interval notation.
False, set builder notation.
What is the output of the function when x = 3
f(x) = 4x -11
f(x) = 4x -11
f(3) = 4(3) -11
f(3) = 12 -11
= 1
Name one interval where the graph is increasing.
[0,5] and [16, 21]
What is the average rate of change for the function: f(x) = 2x -7 between 5 and 1 ?
f(x) = 2x -7
f(5) = 2(5) -7 = 3
f(1) = 2(1) -7 = - 5
-5 - 3 / (1 -5) = -8/-4 = 2
What is the y-intercept in this table?
-1
What interval is f(x) < 0 ? (Show graph)
[3, 7]
Find the value of f(5) - f(0) using the function
f(x) = 6x - 2.
f(5) - f(0)
f(5) = 6x - 2 = 6(5) -2 =28
f(0) = 6x - 2 = 6(0) - 2 = -2
28 --2 = 30
Name one interval where the graph is decreasing.
[10, 13]
Is the following a function? Why or why not?
No, because every x must have exactly one y.
