Y² + 2 y - 2x - 3 = 0
x + 3 = y² + 2 y
2 x + 3 = y²  + 2 x + 1 - 1
2 x + 3 = ( y + 1 )² - 1
2 x + 3 + 1 = ( y + 1 )²
Answer:
2 ( x + 2 ) = ( y + 1 )²

Answer:

The given equation of Parabola is

y^2 + 2 y - 2 x - 3 = 0\\\\ (y+1)^2-1-2 x- 3=0\\\\  (y+1)^2=2 x +4\\\\ (y+1)^2=2(x+2)

The given parabola has vertex equal to (-2,-1).

If written in the form of

Y^2=4 A X

Where , A is the focus ,if the vertex of new parabola is (0,0).

4 A=2\\\\ A=\frac{2}{4}\\\\A=\frac{1}{2}

Coordinates of focus

  =(-2,-1+\frac{1}{2})\\\\=(-2,\frac{-1}{2})

Explain whether the graph represents a function.
aleksley [76]

Answer:

The vertical line test can be used to determine whether a graph represents a function. ... If we can draw any vertical line that intersects a graph more than once, then the graph does not define a function because that x value has more than one output. A function has only one output value for each input value.

Henry received $500 for his birthday which he intends to invest in an account that pays simple interest at the rate of 12% per y
Mila [183]

Answer:

$560

Step-by-step explanation:

Given that :

Principal, P= $500

Interest rate, r = 12% per year

Amount in account after 1 year

Time = 1 year

Using the relation :

A = P(1 + rt)

A = final amount in account

A = $500(1 + 0.12(1))

A = $500(1 + 0.12)

A = $500(1.12)

A = $560
