What is the equation in standard form of a parabola that models the values in the table

nikdorinn [45]

Answer:

Y=4x^2-3x+5

Step-by-step explanation:

For the standard form equation to model the values in the table, each value of x in the table should give the matching the y value when substituted into the equation. We will test each equation:

<u> $Y=-4x^2+3x+5$ for (-1,12)</u>

$Y=-4(-1)^2+3(-1)+5=-4(1)+-3+5=-4+-3+5=-2\\$

This does not give 12 as the answer and is not a solution.

<u> $Y=-4x^2-3x+5$ for (-1,12)</u>

$Y=-4(-1)^2-3(-1)+5=-4(1)+3+5=-4+3+5=4\\$

This does not give 12 as the answer and is not a solution.

<u> $Y=3x^2-4x+5$ for (-1,12)</u>

$Y=3(-1)^2-4(-1)+5=3(1)+4+5=3+4+5=12\\$

This does give 12 as the answer and is a possible solution.

We now try (2,15).

$Y=3(2)^2-4(2)+5=3(4)-8+5=12-8+5=9\\$

This does not give 15 as the answer and is not a possible solution.

<u> $Y=4x^2-3x+5$ for (-1,12)</u>

$Y=4(-1)^2-3(-1)+5=4(1)+3+5=4+3+5=12\\$

This does not give 12 as the answer and is not a solution.

We now try (2,15).

$Y=4(2)^2-3(2)+5=4(4)-6+5=16-6+5=15\\$

This does give 15 as the answer and is a solution.

This is the standard form of the equation.

Just need answer.....

erastova [34]

HEY THERE!!!!

The correct answer is 34°

They are supplementary angles (connect with a straight line) which means that their angles add up to 180° so:

180 = x + 156

34 = x

HOPE IT HELPS AND WOW I MADE IT LOL

Which graph represents the function f(x)= 2x-1/x-1

Effectus [21]

To determine which <u>graph</u> represents the <u>function</u> $f(x)=\dfrac{2x-1}{x-1}$ make following steps:

1. The vertical asymptote is $x=1.$

2. Simplify the function

$f(x)=\dfrac{2x-1}{x-1}=\dfrac{2x-1-1+1}{x-1}=\dfrac{2(x-1)+1}{x-1}=2+\dfrac{1}{x-1}.$

Then the horizontal asymptote is $y=2.$

Only option C contains graph with such asymptotes.

Answer: correct choice is C
