Answer:
option A
f(x) = (x – 1)2 + 3
Step-by-step explanation:
Given in the question a function,
f(x) = 4 + x² – 2x
<h3>Step 1</h3>
f(x) = 4 + x² – 2x
here a = 1
b = -2
c = 4
<h3>
Step 2</h3>
x = -b/2a
h = -(-2)/2(1)
h = 2/2
h = 1
Step 3
Find k
k = 4 + 1² – 2(1)
k = 3
Step 4
To convert a quadratic from y = ax² + bx + c form to vertex form,
y = a(x - h)²+ k
y = 1(x - 1)² + 3
y = (x - 1)² + 3
<h3>
