{x}^{2}  - 2 {x}^{2}  - 4 \\  -  {x}^{2}  - 4

The Quadratic Function has the domain as the set of all real numbers.

For the range, start from minimum value to maximum value.

But because the parabola is downward as a < 0. Thus, there are no minimum value but the maximum value instead.

Therefore the range is y <= -4

solve for the indicated variable. include all of your work in your answer. submit your solution. P=2L+2W; for L.
allochka39001 [22]
We have this equation:

P=2L+2W

So, we need to solve this equation for L. Then we sum -2W in each member of the equation, like this:

P-2W=2L+2W-2W
P-2W=2L

Then, dividing the equation by 2:

\frac{P-2W}{2}=L

Finally, let's order this equation:


L=\frac{P-2W}{2}
