Answer:

2 solutions

Step-by-step explanation:

A quadratic equation has the formula:

ax^{2} + bx +c = 0

The solution of the equation is given as:

x = \frac{-b+\sqrt{b^{2}-4ac } }{2a}

The expression: b^{2}-4ac is known as the discriminant given by the symbol D.

Thus, the discriminant D, is given as D = b² - 4ac

There are several conditions to the solution.

If D < 0 the roots are imaginary. They are not real.  

If D = 0, the solution has one real root

If D > 0, the solution as two distinct real roots (negative or positive)

A quadratic equation has only two real roots or solutions.

Answer: according to spark notes: There can be 0, 1, or 2 solutions to a quadratic equation, depending on whether the expression inside the square root sign, (b2 - 4ac), is positive, negative, or zero. This expression has a special name: the discriminant.

In this case it is 0, not 2, which was my first and wrong answer

Since we are asked to find the rate of change from Monday to Wednesday, we are dividing by 2, since Monday is day 1 and Wednesday is day 3. 3 - 1 = 2.

1800 + 500 = 2300 calories consumed Tuesday.

2300 - 100 = 2200 calories Wednesday.

(2200 - 1800)/2 = 400/2 = 200 calories
