Answer:
domain: -2 < x < 4
range: -∞ < y < 9
Step-by-step explanation:
domain: because the domain is all of the x-values, just look for the furthest one to the left, which is -2, and then look for the one that is furthest to the right, it being 4.
range: because the quadratic function has the two arrows continuing downwards, toward the negative portion of the graph, it would be -∞. Then look for the maximum of the graph, which would be considered the most highest part of the graph, which is seen on the graph as 9.
Answer:
D.
Step-by-step explanation:
Step 1: Write slope-intercept form
y = mx + b
Step 2: Solve for <em>m</em>
- Subtract b on both sides: y - b = mx
- Divide both sides by x: (y - b)/x = m
- Rewrite: m = (y - b)/x
Answer:
1) Please see the required graph created with Microsoft Excel
2) No
Step-by-step explanation:
The given parameters are;

From the given equation, we have;
When x > 4, or x -2 <, y < 0, which gives;
y > 0 for -2 < x < 4
Therefore, the graph is opened in the downward direction with the peak at the point with coordinate (1, 3)
The legs of the graphs are straight lines with slopes = -1, and 1 respectively, before and after the maximum point of the graph
The table of values used to sketch the graph with Microsoft Excel is given as follows;
x
y
-3 -1
-2 0
-1 1
0 2
1 3
2 2
3 1
4 0
5 -1
