Marsha wants to determine the vertex of the quadratic function f(x) = x2 – x + 2. What is the function’s vertex? (one-half, seven-quarters)
(one-half, three-halves)
(1, 1)
(1, 3)

Step-by-step explanation:

Given

Required

The vertex

We have:

First, we express the equation as:

Where

So, we have:

--------------------------------------------

Take the coefficient of x: -1

Divide by 2: (-1/2)

Square: (-1/2)^2

Add and subtract this to the equation

--------------------------------------------

Expand

Factorize

Factor out x - 1/2

Compare to:

Hence:

560
