ASAP! find the inverse of the function y=2x^2+2

jeka57 [31]

Answer:

$\displaystyle y=\sqrt{\frac{1}{2}x -1}$

Step-by-step explanation:

We want to find the inverse of the function:

$y=2x^2+2$

To find the inverse of a function, we will flip the variables and solve for <em>y</em>. So:

$x=2y^2+2$

Solve for <em>y</em>. Subtract two from both sides:

$x-2=2y^2$

Divide both sides by two:

$\displaystyle y^2=\frac{1}{2}x-1$

And take the principal square root of both sides. Therefore:

$\displaystyle y=\sqrt{\frac{1}{2}x -1}$

What is the perimiter, in feet, of a square whose area is 121 square feet

Ainat [17]

Square needs to have all equal sides and length and width are the same.

So sqrt the area.

sqrt 121 = 11

11 feet is the length of one side, square has 4.

11 * 4 = 44

The perimeter of a square (whose area is 121 feet) is 44 feet.

what ordered pair is 2 spaces to the left and 4 spaces down from the point graphed on the coordinate plane?

kykrilka [37]

C. (-1, -2) would be your answer
That transformation is just a translation (x-2, y-4) from point (1,2)
