Hello from MrBillDoesMath!
Answer:
x^3 - 6 x^2 - x + 6
Discussion:
The polynomial is
(x-1) (x - (-1)) (x-6) =
(x-1)(x+1)(x-6) = => as (x-1)(x+1) = x^2 - 1
(x^2-1)(x-6) =
x^2(x) - 6 x^2 - 1x + 6 =
x^3 - 6 x^2 - x + 6
Thank you,
MrB
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
In the time period of three years, she would shrink .75 cm or 3/4 cm.
