10
Step-by-step explanation:
Answer:
The discriminant is the expression b2 - 4ac, which is defined for any quadratic equation ax2 + bx + c = 0. Based upon the sign of the expression, you can determine how many real number solutions the quadratic equation has. If you get a positive number, the quadratic will have two unique solutions

Answer:
A. f(x) = 2x + 1.
Step-by-step explanation:
5 = 2(2) + 1
11 = 2(5) + 1
17= 2(8) + 1
23 = 2(11) + 1
- so it is f(x) = 2x + 1.
Answer:
It is function.
Step-by-step explanation:
Function is they don't have same repeating x values in tables, graphs, and coordinates. In this question, they give you the equation. But if you look at closely, it is linear equation! That means that when you graph this equation, you will get straight line. So, straight line can't get same x values, it is function.
