What is the output value for the following function if the input value is 3.2?
y = 2 x - 1

1
2
4.2
5.4

Do not comment if you aren’t going to . create a real-life situation and create a system and show how it might be modeled algebraically with a system of equations (or inequalities) show all work include a few sentences explaining the situation, your variables of choice and what each represents, and how you would set it up and solve it algebraically. !

Evaluate the discriminant of each equation. tell how many solutions each equation has and whether the solutions are real or imaginary. x^2 - 4x - 5 = 0

The roots of the function f(x) = x2 – 2x – 3 are shown. what is the missing number?
