Answer:
Step-by-step explanation:
for c- start at 0, go to the left and stop right above the zero. do not put a point. then go down and stop in between -2 and -3. put a point
For D- start at zero. go to the right and stop between the four and the end of the line. Do not put a point. Then go up one box. put a point.
Hi!
When adding and subtracting negative numbers, just imagine a number line.
For example, let's say we're adding 3 + -7.
Tip: Adding negative numbers is the same as subtracting positive numbers. So 3 + -7 is the same as 3 - 7.
Here's a numberline:
-10, -9, -8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5
Now add 3 to negative 7. (or subtract 7 from 3)
-10, -9, -8, -7<em>, -6, -5, </em><em>-4</em><em>, -3, -2, -1, 0, 1, 2</em>, 3, 4, 5
3 + -7 = -4
Let's try subtracting now. How do we solve 5 - (-3)?
Tip: Subtracting a negative is the same as adding a positive. So 5 - (-3) is the same as 5 + 3. Another way of thinking of it, is two minuses make a positive.
Numberline:
-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5
Subtract -3 from 5. (or add 12 to 5)
-5, -4, -3, <em>-2, -1, 0, 1, 2, 3, 4, </em>5<em>, 6, 7, 8</em>, 9, 10
Here are a few more examples.
-7 + -3 (which is the same as -7 - 3) = -10
-8 + 6 = -2
-9 - (-8) (which is the same as -9 + 8) = -1
-9 - 3 = -12
Hope this helps! :)
ANSWER
A) The algebraic function has a greater maximum value.
EXPLANATION
The given function is
This can be rewritten as:
The maximum value of this function is 2.5
The maximum value of the graph is less that zero.
This means that that the maximum value of the algebraic function is greater than the maximum value of the graph.
