The following is the graph of a quadratic friction, find the value of x when y = 0
-
A.
1, 2 -
B.
1, 4 -
C.
2, 3 -
D.
1, 6
Correct Answer: Option B
Explanation
when y = 0, value of x = roots of the equation
x2 – 5x + 4 = 0
x = 1, 4 (see graph)
when y = 0, value of x = roots of the equation
x2 – 5x + 4 = 0
x = 1, 4 (see graph)
