If y = x2 – 2x – 3, Find the least value of y and corresponding value of x
-
A.
x = 3, y = 3 -
B.
x = 1, y = -3 -
C.
x = 4, y = 1 -
D.
x = 1, y = -4 -
E.
x = 2, y = -3
Correct Answer: Option D
Explanation
If the graph of eqn. y = x2 – 2x – 3 is plot and drawn, the lease value of y = -4 while the corresponding value of x = 1
x = 1, y = -4
