Answer:
Positive
Step-by-step explanation:
Since there are two x-intercepts, -2 and 2, there is a positive discriminant. If the parabola was below the x axis and opened downwards, the discriminant would be negative.
Answer:
So, the relation between variables are

Step-by-step explanation:
We are given

Since, we have to find relation between variables
so, we can solve for y

Firstly, we will multiply both sides by y

we can simplify it

we can isolate y
so, we can divide both sides by 7
so, we get

Answer:
7/12
Step-by-step explanation:
4 x 3 = 12 (LCD)
3/12 + 4/12 = 7/12
No simplifying done,
7/12 is the answer.
Hope this helped :)
