Calculate the discriminant of the following quadratic equation, then use your answer to determine how many real solutions the equation has:
y = 2x2 + 3x - 5
The discriminant is 49. Since 49 > 0 we know our solution set will consist of two real numbers.

Which of our three regression models that we've studied (linear, quadratic, or exponential) fits the data in the table below the best. Must justify answer to receive points.
The exponential model is the best fitting model because it produces the highest R2-Value.
