The two lines coincide. The two equations have the same slope and intercept. If you multiply the second equation by 3, you’ll get the first equation.

What is the focus of the parabola? y=−1/4x2−x+3

alex41 [277]

Answer: Focus = (-2, 3)

<u>Step-by-step explanation:</u>

$y=-\dfrac{1}{4}x^2-x+3\\\\\rightarrow a=-\dfrac{1}{4},\ b=-1$

First let's find the vertex. We do that by finding the Axis-Of-Symmetry:

$AOS: x=\dfrac{-b}{2a}\quad =\dfrac{-(-1)}{2(\frac{-1}{4})}=\dfrac{1}{-\frac{1}{2}}=-2$

Then finding the maximum by inputting x = -2 into the given equation:

$y=-\dfrac{1}{4}(-2)^2-(-2)+3\\\\y=-1+2+3\\\\y=4$

The vertex is: (-2, 4)

Now let's find p, which is the distance from the vertex to the focus:

$a=\dfrac{1}{4p}\\\\\\-\dfrac{1}{4}=\dfrac{1}{4p}\\\\\\p=-1$

The vertex is (-2, 4) and p = -1

The focus is (-2, 4 + p) = (-2, 4 - 1) = (-2, 3)

sergiy2304 [10]

Answer:

m = -1

b = 3

Step-by-step explanation:

This equation is in slope intercept form: y = mx + b

m is the slope

b is the y intercept

m = -1

b = 3

Answer and tell me how you got answer thanks.

postnew [5]

Answer:

A) {-1,2}

Step-by-step explanation:

square both side of the equation. Then:

x+2=x^2

simplify:

x^2-x-2=0

factor:

(x+1)(x-2)=0

then:

x=-1, x=2
