Question
A particle moves along the curve y = x2 + 2x Then the points on the curve are the x and y coordinates of the particle changing at the same rate, are-
Options
A.
B.
C.
D.
Solution
y = x2 + 2x
given
= 1
y = x2 + 2x
= (2x + 2) × 
= 2x + 2 1 = 2x + 2
x = -
; y = -3/4 Points is 
given
= 1y = x2 + 2x
= (2x + 2) × = 2x + 2 1 = 2x + 2x = -
; y = -3/4 Points is Create a free account to view solution
