Use the information given to write the equation for the quadratic function.
a. The x-intercepts are (-4, 0) and (3,0), and the parabola opens down.
b. The vertex is (-8, -2), and the parabola opens up.
Answer:
y = -x² - x/22 + 6/11
Step-by-step explanation:
Standard form, is y = ax² + bx + c
We need to use standard form (though we could use vertex form, but it is easier to do standard form)
Substitute the x and y values that they give into y = ax² + bx + c
Because the parabola passes through...
(-4, 0), then 0 = (-4)²a + (-4)b + c
(3, 0), then 0 = 9a + 3b + c
(-8, -2), then -2 = 64a - 8b + c
So, we get this system:
16a − 4b + c = 0
9a + 3b + c = 0
64a − 8b + c = −2
Because you are learning about parabolas, I am assuming that you can solve a system, but the answers are:
a = -x²/22
b = -x/22
c = 6/11
So, the equation of the parabola is:
y = -x²/22 - x/22 + 6/11
I hope this helps! Feel free to ask any questions!

This is complicated
Step-by-step explanation:
UHM
Solve y =-2x
y = 3x + 5
by using substitution method
Answer:
y = -2x
y = 3x + 5
<=> 3x + 5 = -2x
y = -2x
<=> 5x = -5
y = -2x
<=> x = -1
y = -2x
<=> x = -1
y = (-2)(-1) = 2
so (x; y) = (-1; 2)

Answer:
(2,-3)
Step-by-step explanation:
Aside from the solution below, you can also do this without needing a coordinate plane.
When you need to move right, you know that you will be only dealing with the x-axis, so the -3 will stay the same, untouched, (x, -3)
From now on, simply add +7 to -5 and you get (2,-3)

What is the complete factorization of 36y2 - 1?
Answer:
(6−1)(6+1)
Step-by-step explanation:
9514 1404 393
Answer:
B. (6y +1)(6y -1)
Step-by-step explanation:
The factorization of the difference of squares is ...
a² -b² = (a +b)(a -b)
Your expression is the difference of the squares ...
(6y)² -1²
so the factorization is ...
36y² - 1 = (6y +1)(6y -1) . . . . . matches choice B
