1 answer:
Talja [164]3 years ago
7 0

Answer:

see below

Step-by-step explanation:

domain is all x values for which a graph has
and range is all y values for which a graph has

domain in this case is -4<x<4. The range is -3<= x <= 3

Function is increasing when slope of the line is positive, function is decreasing when slope of the line is negative.

When 2 lines meet and there is an edge like at (-1,3) there is no increase of decrease of the function. If you are in calculus, this is because the derivative of the function will not be valid at those points. If you are not in calculus, then don't pay attention to the derivative stuff.

Function is increasing on interval -4<x<-1 and 2<x<4
Function is decreasing on interval -1<x<2

(NEED A QUICK ANSWER) Which statement about perfect cubes is true?
kotegsom [21]

Answer:

512 is a perfect cube because 512 = 8 times 8 times 8

Step-by-step explanation:

A perfect cube is a number that can be rewritten as a product of three identical numbers.

For example: 8 is perfect cube as 8 can be rewritten as:

8 = 2 × 2 × 2

So, from the definition of the perfect cubes, the option that matches it is third option.

512 is a perfect cube as it can be expressed as the product of 8 three times.

512 = 8 × 8 × 8

Therefore, third option is correct.

All the remaining options doesn't fulfill the definition of perfect cubes.

PLZ ANSWER THIS<br> THERE IS A SCREENSHOT
allsm [11]

Answer:

-3,-2.4,-2 \frac{1}{4}-1.5,-1 \frac{1}{8}

This means that the answer is the second option.

Step-by-step explanation:

First, lets convert everything to its decimal form.

-2 \frac{1}{4} =-2.25

-1 \frac{1}{8} =-1.125

Now we have the numbers: -2.4,-1.5,-2.25,-3, -1.125

As all of these numbers are negative we could look at each of these numbers as if they were positive and put them in descending order

This means that the order would be

-3,-2.4,-2.25,-2.5,-1.125

The last thing we need to do is change those two decimals back to their mixed number forms

-3,-2.4,-2 \frac{1}{4}-1.5,-1 \frac{1}{8}
