Answer:
2 real solutions
Step-by-step explanation:
Since the degree of the polynomial is 2, then there are 2 solutions for the equation, but we don't know if they are both complex or both real.
Since the discriminant is , then there are 2 real solutions.
Answer:
The rate of change is 1
Step-by-step explanation:
In order to calculate the rate of change, take two points (in this example I'll use points (8, 2) and (10, 4)) and input them into this expression used to calculate rate of change:
Solve:
4 - 2 = 2
10 - 8 = 2
2/2 = 1
The rate of change is 1.
Hope this helps :)
