Let f(x) = 2x^2-2 for 2 < x < 5

Those are less than and equal to and greater than and equal to signs. So how do you find the range in interval notation. I tried graphing it but it just confused me. Thanks.

Ok, the problem is as below:

What number is described

*Each digit in the ones period is 0.
*Each digit in the thousands period is 3.
*The digit in the millions place is twice the digit in the thousands place.

The choices are:
F. 6,003,000
G. 6,333,000
H. 6,633,000
j. 7,333,000

Ok, I know J is eliminated, but that leaves F, G, and H, that I don't believe was enough information to gather the answer on...what do you say is the answer?

John has 300 feet of lumber to frame a rectangular patio (the perimeter of a rectangle is 2 times length plus 2 times width). He wants to maximize the area of his patio (area of a rectangle is length times width). What should the dimensions of the patio be, and show how the maximum area of the patio is calculated from the algebraic equation.

Show clearly the algebraic steps which prove your dimensions are the maximum area which can be obtained. Use the vertex form to find the maximum area.
