dolphi86 [110]
Vertex form:
y-k=a(x-h)^2
h=-2,k=-20,y=-12 when x=0
thus;
-12+20=a(0+2)^2
8=4a
a=2
Equation:
y+20=2(x+2)^2
y+20=2(x^2+4x+4)
f(x)=2(x^2+4x+4)-20
f(x)=2x^2+8x+8-20
f(x)=2x^2+8x-20

Which function describes this table of value x -8, -4, 4, 8, y -2, 0, 4, 6
nadezda [96]

we conclude that the linear equation represented by the given table is:

y = (1/2)*x + 2

<h3>Which function is the one described by the table?</h3>

A general linear equation is given by:

y = a*x + b

Where a is the slope and b is the y-intercept.

If the line passes through (x₁, y₁) and (x₂, y₂), then the slope is given by:

a = \frac{y_2 - y_1}{x_2 - x_1}

Here we can use just the first two points on the given line:

(-8, -2) and (-4, 0)

Then the slope will be:

a = \frac{0 - (-2)}{-4 -(-8)}  = \frac{2}{4} = \frac{1}{2}

Then the linear equation is something like:

y = (1/2)*x + b

To find the value of b, we can use one of the two given points, I will use (-4, 0), then:

0 = (1/2)*(-4) + b

0 = -2 + b

2 = b

Then we conclude that the linear equation represented by the given table is:

y = (1/2)*x + 2

Then the correct option is the first one.
