Please help! To determine the interval in which a function is increasing. Graph the function using a graphin calculator OR your
knolwedge of parent functions and thier transformations OR create a table of values (aka T-Chart) to help you determine what points to plot on your graph.
Once you have a graph of your function, you can then look to find the portion of your graph where it is increasing (moving upwards to the right).
For the function below, we see that the function is increasing on the interval [0,∞)
This means that when you look at the graph you will see it begin to increase when x=0 and all values towards the right.
On a number line we would show the interval where the function is increasing indicated with the red arrow pointing to the right of 0 since our function is increasing from 0 to infinity.
At what interval is the function is decreasing. (ie moving downwards from the upper left side) ?
A(-3,0]
B(-∞ ,0]
C(-4,0)
D(-1.5, 1.5)
