The graph of the function y = x\(^2\) + 4 and a straight line PQ are drawn to solve the equation x\(^2\) - 3x + 2 = 0. What is the equation of PQ?
A
y = 3x - 2
B
y = 3x + 2
C
y = 3x - 4
D
y = 3x + 4
Verified Correct Answer: B.
Step-by-Step Mathematical Solution
x\(^2\) + 4 = x\(^2\) - 3x + 2
3x + 2 = y
