Hope it helps!
Step-by-step explanation:
The graphs of quadratic functions are called parabolas. Here are some examples of parabolas. All parabolas are vaguely “U” shaped and they will have a highest or lowest point that is called the vertex. Parabolas may open up or down and may or may not have x -intercepts and they will always have a single y -intercept.
The graph of a quadratic function is a U-shaped curve called a parabola. The sign on the coefficient a of the quadratic function affects whether the graph opens up or down. If a<0 , the graph makes a frown (opens down) and if a>0 then the graph makes a smile (opens up).

Answer:
486²in
Step-by-step explanation:
9×9=81 (gives you one face of the cube)
81×6=486 (there are 6 faces on a cube)
Answer: all of them they are negitive numbers
Step-by-step explanation:
2(3x + 4) / 2(2x + 2)
Cancel the factored 2s
3x + 4 / 2x + 2
You may need to further factor the denominator, depending on the teacher.
3x + 4 / 2(x + 1)
It depends on which definition of 'whole numbers' you use.
<span>Some definitions say the whole numbers are the set of positive integers including zero; or the set of all non-negative integers. In this case, the answer would be 'false', since the set of integers includes negatives. </span>
<span>However, if you are using a definition of whole numbers which includes positive integers, including zero, and their negatives, the answer would be 'true'. Figure out how the term 'whole numbers' is being defined, then you can get your answer.
Hope this helped you. :)
