How do you write the vertex form equation of the parabola #y=2x^2 +11x-6#?

liubo4ka [24]

The easist way to find the vertex is to complete the square:

y=2x^2 +11x-6 => <span>y=2[ x^2 + (11/2)x + (11/2)^2 - (11/2)^2 ] - 6

This can be rewritten as
y = 2[(x+11/2)^2 ] -(121/4) - 24/4

y = 2 (x+11/2)^2 - 145/4

this is the equation in vertex form. The vertex is at (-11/2, -145/4).</span>

Consider the graph above. Write about a situation that could be modeled using this graph. In your response, use the prompts belo

Vikentia [17]

Answer:

See Explanation

Step-by-step explanation:

Given

See attachment for graph

Required

A situation that can be modeled by the graph.

The prompt and the response are as follows:

<u>The type of function:</u>

It is a linear function

<u>The variables modeled in the function</u>

The variables are x and y

<u>The domain and the range</u>

From the graph, we can see that x and y values are not limited to any constraints.

So, the domain and the range are:

$Domain: \{-\infty \le x \le \infty \}$

$Range: \{-\infty \le y \le \infty \}$

<u>Question that could be </u> $answered$ <u></u>

The graph could be used to predict y value, given the x value.

Take for instance, find y when x = 10

The answer can be handpicked directly from the graph. However, the best way is to calculate the graph equation, first.

So, we have:

Pick any two points on the line of the graph

$(x_1,y_1) = (-2,0)$

$(x_2,y_2) = (0,4)$

Calculate the slope (m)

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{4 - 0}{0 - -2}$

$m = \frac{4}{2}$

$m =2$

The equation of the graph is:

$y = m(x - x_1) + y_1\\$

So, we have:

$y = 2(x - -2) + 0$

$y = 2(x +2)$

Expand

$y = 2x +4$

To solve for y when x = 10;

$y = 2 * 10 +4$

$y = 20 +4$

$y = 24$
