Determine if the function is linear or nonlinear. Justify your answer.
Nonlinear: it is not a straight line.
Determine which intervals are increasing, decreasing, or constant.
Inc: 2, 4, 6 / Dec: 1, 5 / Const: 3, 7
Give the function and the domain, find the range
R: {6, 8, 9}
Is this a function or not? Explain
No, it fails the VLT at x=0.
What is the domain of this relation?
D: {0, 1, 2, 4}
Compare the rates at which Mochi and Kappa are growing
Mochi starts off smaller than Kappa (1 lb at 0 weeks vs 2 lbs at 0 weeks) but Mochi is growing faster than Kappa because he is more than Kapp at 3 weeks (13>11)
Find x, given f(x) = -3
x = 3
Given the graph, find f(-5) and f(2)
f(-5) = 2 and f(2) = -1
Evaluate the following function
f(-1)= -3
Determine the coordinate points of the maximum and minimum points.
Max: (2, 4), Min: (-2, -4)
Given the graph, find f(-3) and f(0)
f(-3) = 0 and f(0) = 3
What is the domain & range of this relation?
Domain: {-4, 1, 5, 6} , Range: {0, 1, 2}
Determine if the relation is linear or nonlinear. Justify your answer.
Linear: x increases at a constant rate (+3) and y increases at a constant rate (-4).
Write an equation in slope-intercept form to represent the function (y=mx+b)
y = (3/2)x + 3
Determine if the relation is linear or nonlinear. Justify your answer.
Linear: x increases at a constant rate (+5) and y increases at a constant rate (+3).
Is this a function or not? Explain.
Yes - every x is paired with only one y
The graph represents the speed of a vehicle over time. Explain what the changes in the graph represent about the speed of a vehicle.
The car started off at a constant speed, then it slowed down coming to a spot. The car then sped up very quickly & slowed down very quickly, coming to a stop.
What is the range of this relation?
R: {-2, 1, 2, 4}
