Step-by-step explanation:
See picture for explanation.
Answer: B. 4.5 X 0.72
x= 0, y=2
x=2, y=-2
x=4, y= -5
let's put value of t in equation.
x = 2√t
x = 2√y
x/2 = √y
(x/2)^2 = y
y = x^2 /4
now let's differentiate it with respect to x.
dy/dx = 2x/4 = x/2
differentiating again wrt to x
d^2y/dx^2 = 1/2
