Answer:

The range of the function h(x) is all even integers.

Step-by-step explanation:

Range is the set of outputs and y values.

It is given that the function h(x) is represented by y = –2⌊x⌋.

Here, ⌊x⌋ represent the greatest integer function.

The greatest integers function is

$f(x)=\begin{cases}-1 & \text{ if } -1\leq x$

Range of a greatest integer function is all integers.

The function is 2 times of greatest integer function.

$h(x)=\begin{cases}2(-1) & \text{ if } -1\leq x$

Therefore the range of h(x) is all even integers.

The value of step function is an integer number from negative infinity to positive infinity. So the phrase is "all the integer numbers, Z".

We are asked to express the diagonal of a rectangle in terms of the width in which the area of the polygon is equal to 13 square feet. The area of teh rectangle is equal to length times width. That is 13 = lw; diagonal using pythagorean theorem is sqrt ( l2 + w2). Thus d = sqrt ( (13/w)2 + w2) = sqrt ( (169/w2 + w2) = sqrt ( (169 + w4)/w2) = 1/w sqrt (169 + w4)
