Question

Marsha wants to determine the vertex of the quadratic function f(x) = x2 – x + 2. What is the function’s vertex?

Answer 1

The formula for finding the vertex of a parabola is: x = -b/2a
Once you find the x value, substitute it back in to the function to find the y value.
x = 1/(2*1)
x = 1/2

y = (1/2)^2 -(1/2) + 2
y = (1/4) - (1/2) + 2
y = 1 3/4
vertex (1/2, 1 3/4)
