Next time, please try to make your question more specific.
g(x)= -2x^2+5 is a modification of f(x) = x^2 (a parabola with vertex at (0, 0) and opening up).
If f(x) = x^2 is graphed, we can translate its shape up, down, right or left.
In g(x)= -2x^2+5, this graph has been translated up by 5 units, inverted (so that it now opens down), and vertically stretched by a factor of 2.

Question 19
<h3>Answer: No, it is not in quadrant 3.</h3>
Explanation:
In order to be in quadrant 3, we need two things
- x must be negative
- y must be negative
An example point in the third quadrant is (-9, -12).
Both (x,y) coordinates must be negative to be located in quadrant 3. This is the southwest quadrant on the xy grid. We're told that x = 0 which means we are not in quadrant 3. Points on the x or y axis are not part of any quadrant. They are on the boundaries between quadrants (think of it like a fence or a wall).

Question 20
<h3>Answer: No, it is not in quadrant 2</h3>
Explanation:
We use a very similar idea as the previous question. Since y = 0, this point is on a boundary and not in any quadrant. To be in the second quadrant, we need these two conditions to be true:
- x must be negative
- y must be positive
For example, the point (-5, 7) is in quadrant 2. This quadrant is in the northwest on the xy grid.
Answer:
a) 5 x² + 3 x -10
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given polynomials
3 x² - 5 x + 1 and 8 x² - 2 x -9
Given that
3 x² - 5 x + 1 From 8 x² - 2 x -9
⇒ 8 x² - 2 x -9 - ( 3 x² - 5 x + 1 )
= 8 x² - 2 x -9 - 3 x² + 5 x - 1
= 5 x² + 3 x -10
