Question 443358
The leading coefficient of the highest power term (x^2) is positive for each quadratic. This means, when x gets very large, y will tend to go to infinity, so there is no maximum.


The x-coordinate vertex of the quadratic in the form *[tex y = ax^2 + bx + c] is -b/2a. Evaluate this number, then replace it to find the maximum or minimum value (in this case, minimum).
