(30pts)(i need it quick)find the inverse of the given function:

Rewrite your function in terms of x and y. Then solve for y in terms of x:

y = -1/2 * (sqrt(x+3)

-2y = sqrt(x+3)

4y^2 = x +3

x = 4y^2-3

Now swap x and y.

y = 4x^2-3

So you got the correct answer. To determine the domain, look back at the original function:

y = -1/2 * (sqrt(x+3), x ≥ -3

We see that x must be greater or equal to -3 in order for the square root to be a real number. Thus sqrt(x+3) must be nonnegative, by that I mean positive or zero.

So if that part of our function is positive and then we are multiplying it by -1/2, our function will only output a nonpositive number, by that I mean either negative or zero. That means our range for this function is y ≤ 0.

And by definition of the inverse, the range of the original function becomes the domain of the inverse. That means the domain of our inverse is x ≤ 0.

I hope that makes sense!

answer: yard ramps with a level off platform are typically 36 feet long. truck, rather than at an angle, enabling access to those pallets at the very back of the truck. if you are using your yard ramp to convert a loading dock into a drive-in door, we even at 60 inches (5 feet) high and a 30 foot ramp, the slope of the ramp will be less
