Please help!!! The sum of three consecutive integers is 9.​
Travka [436]

Answer:

2

Step-by-step explanation:

because they're consecutive, each integer has to come right after the one before it.

if 1st integer is 1, the 2nd should be 2, and the 3rd should be 3.

3 is equal to 1 + 2, or n + 2

hopefully that works

Rhianna says she can draw different functions that have the same x‑intercepts and the same domain and range. Her teammates say,
qwelly [4]

In both cases there are more than one possible function sutisfying given data.

1. If

  • x‑intercepts are (–5, 0), (2, 0), and (6, 0);
  • the domain is –5 ≤ x ≤ 7;
  • the range is –4 ≤ y ≤ 10,

then (see attached diagram for details) you can build infinetely many functions. From the diagram you can see two graphs: first - blue graph, second - red graph. Translating their maximum and minimum left and right you can obtain another function that satisfies the conditions above.

2. If

  • x‑intercepts are (–4, 0) and (2, 0);
  • the domain is all real numbers;
  • the range is y ≥ –8,

then you can also build infinetely many functions. From the diagram you can see two graphs: first - blue graph, second - red graph. Translating their  minimum left and right you can obtain another function that satisfies the conditions above.

Note, that these examples are not unique, you can draw a lot of different graphs of the functions.

Answer: yes, there are more than one possible function
