Answer:
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:
Question: Marsha wants to determine the vertex of the quadratic function f(x) = x2 – x + 2. What is the function’s vertex?
Answer: A or 1/2 , 7/4
did it on an assignment on EDGE
<em>3.1405</em>
= 1 ⇒ This is always the case
So,
3.1405 × 1 = 3.1405
