Find the discriminant of 5x^2+3x-5=0 for x

For this case we have that by definition, a quadratic equation is of the form:

Its roots are given by:

By definition, the discriminant is given by:

According to the given equation we have to:

Substituting:

The discriminant is 109

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.
