What equation is the inverse of y=2x^2-8?

Fynjy0 [20]

Step-by-step explanation:

To get the inverse, swap the x- and y-variables, then solve for y. We should have the equation: $x = 2y^2 - 8$

Solving for y:

$y = 2x^{2} - 8$ because $y + 8 = 2x^{2}$ or $x =\sqrt\frac{y + 8}{2}$

So on interchanging the variable, we get the equation:

$x = 2y^2 - 8$

$x + 8 = 2y^2$

$y = \sqrt\frac{x + 8}{2}$

Which choice is equivalent to the product below when x > 0?

anastassius [24]

The product below is equivalent when x > 0 is <u>1/9</u>

<h3>Resolution - Explanation</h3>

Square root is a real number x multiplied by itself - which results in a perfect value, where it is possible to calculate the real proof (which is the square root).

Given the expression, $\large \sf \sqrt{\dfrac{1}{x^{2} } } \cdot \sqrt{\dfrac{x^{2} }{81} }$ , first step: we will calculate the root of the numerator and denominator of this fraction:
