3
Determine the following:
Domain: all the x-values
-> always (- ∞, ∞) for non-story problems
Range: all the y-values
-> need the y-value of the vertex
-> [4, ∞)
4
Increasing Intervals
Find the AoS and decide which side goes uphill (from L to R)
Find the x-value of the vertex
Is this the end or the start of the interval?
It will either be (- ∞, #) or (#, ∞)
Increasing: (1, ∞)
5
Decreasing Intervals
Find the AoS and decide which side goes downhill (from L to R)
Find the x-value of the vertex
Is this the end or the start of the interval?
It will either be (- ∞, #) or (#, ∞)
Decreasing: (- ∞, 1)
6
Intercepts
y-intercepts: hit the y-axis
(0, 0)
x-intercepts: hit x-axis
(0, 0) and (1, 0)
7
Rate of Change (ROC)
Find the rate of change [1, 2]
Find the rate between x-values of 1 and 2
Find points on graph and find the rise and the run
Rise: 4 Run: 1
ROC: 4/1 or 4
