Answer:
just multiply all the points by 3
Step-by-step explanation:
the new points are
(-9,9) (-3,9)
(-9,-3) (-3,3)
I don't have a way to post a picture of it graphed. Sorry. I hope this helps!
Answer:
x=5
Step-by-step explanation:
5-3=2
Answer:
0.375 is 1/8 of 3. 3 groups of 1/8 is 3/8. 0 3's are in 1/8.
Step-by-step explanation:
Answer:
y=1
Step-by-step explanation:
there is no slope therefore dont place it. however there is a Y intercept.
Given:
The image of a lens crosses the x-axis at –2 and 3.
The point (–1, 2) is also on the parabola.
To find:
The equation that can be used to model the image of the lens.
Solution:
If the graph of polynomial intersect the x-axis at c, then (x-c) is a factor of the polynomial.
It is given that the image of a lens crosses the x-axis at –2 and 3. It means (x+2) and (x-3) are factors of the function.
So, the equation of the parabola is:
...(i)
Where, k is a constant.
It is given that the point (–1, 2) is also on the parabola. It means the equation of the parabola must be satisfy by the point (-1,2).
Putting in (i), we get
Divide both sides by -4.
Putting in (i), we get
Therefore, the required equation of the parabola is .
Note: All options are incorrect.
