What is the discriminant of the quadratic equation 0 = -x2 + 4x – 2?

8

Step-by-step explanation:

The discriminant  is

b^2 -4ac  

where a is the x^2 coefficient, b is the x coefficient and c is the constant

-x^2 +4x -2

a = -1   b=4  and c = -2

4^2 -4(-1) (-2)

16 - 8

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.
