Answer:

f(x) = 3x2

Step-by-step explanation:

I think the given the scatter plot is missing and it is my attachment for your question.

My answer:

f(x) = 3x2, it is a parabolic pathway. a =3 (positive) so the line is going up.

The other options are straight lines so they are wrong.

n your notebook, set up the following subtraction in a vertical format and select the correct answer. Reduce 7y + 2y 2 - 7 by 3

exis [7]

Answer:

$\frac{2y^2+7y-7}{3-4y}$

Step-by-step explanation:

We are given

$\frac{7y+2y^2-7}{3-4y}$

we can rewrite it as

$\frac{2y^2+7y-7}{3-4y}$

we know that

2y^2+7y-7 can not be factored

so, we can not reduce this expression

because this is the only way to reduce it

so, we get reduced form as

$\frac{2y^2+7y-7}{3-4y}$

X^2-x+2=0 Please use the quadratic formula

Ainat [17]

Answer:

$\boxed{\sf x=\cfrac{1\pm \sqrt{-7} }{2}}$

Step-by-step explanation:

$\sf x^2-x+2=0$

Use quadratic formula:

$\boxed{\sf \frac{-b\pm \sqrt{b^2-4ac}}{2a}}$

$\sf a=1, b=-1, c=2$

___________________________

$\sf x_1,_2=\cfrac{-\left(-1\right)\pm \sqrt{\left(-1\right)^2-4\times \:1\times \:2}}{2\times \:1}$

$\sf \sqrt{\left(-1\right)^2-4\times \:1\times \:2}$

$\sf =\sqrt{-7}$

_________________

$\sf x_1,_2\cfrac{-\left(-1\right)\pm \sqrt{-7}}{2\times \:1}$

$\sf -(-1)=1$

$2\times 1=2$

$\sf x_1,_2=\cfrac{1\pm \sqrt{-7} }{2}$
