Astep function h(x) is represented by y = –2⌊x⌋. which phrase best describes the range of the function h(x)?

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

Range of a greatest integer function is all integers.

The function is 2 times of greatest integer function.

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

true

explanation:

you are playing an adventure game on your computer. you come across a troll who won't let you pass and there is no other way to get to the other side of the river except over the bridge he is guarding.

the troll is a nerd. he takes great delight in watching people struggle with his problems. very few get them. he only gives you one chance and then he changes the puzzle. you have to solve this one.

before you are four blocks. they are numbered 11,6, -7,21.

he tells that the answer he wants is minus and between -1 and - 2. you can use +, -, ×, ÷   ( and ) as many times as you like or no times at all. you don't like the way he's looking at you, but you need to cross the bridge. what do you do?
