Question 1047075: Please help me solve this equation
Determine, without graphing, whether the given quadratic function has a maximum value or a minimum value and then find that value. f(x) = 2x2 - 2x
Answer by josgarithmetic(39616) (Show Source): You can put this solution on YOUR website!
f(x) = 2x2 - 2x

You mean to say, f(x) = 2x^2 - 2x

which will become rendered as .

Is the coefficient on the leading term positive, or is it negative? Vertex minimum if this coefficient is positive.

So you have your answer.
-------you know the lead coefficient is positive. The reference model parabola equation is , and you already know what this looks like graphed:

and what if the lead coefficient were 2 instead of 1, still positive?
