What is the value of the discriminant, b2 4ac, for the quadratic equation 0 = x- - 4x + 5, and what does it mean about the number of real solutions the equation has?
O The discriminant is -4, so the equation has 2 real solutions.
The discriminant is -4, so the equation has no real solutions.
O The discriminant is 35, so the equation has 2 real solutions.
O The discriminant is 35, so the equation has no real solutions.

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
