Question

Find the y-coordinate of the vertex of the parabola whose equation is y = x^2 - x + 2.

2 1/4?

Answer 1

Find the x-value of the vertex from x = -b/2a
Then compute f(x)
x = 1/2
y = 1/4 - 1/2 + 2 = ?

Answer 2

Best advice: don't just look at a list of 4 choices and guess. Instead, compute!

Answer 3

theres no choices in my textbook..
=2?

Answer 4

Sorry, I just supposed that. Seems like most people have multiple choice. No choices is good in my opinion.
