The second part(b) says to calculate the first and second differences of the equation
Type it exactly as it is written please. In particular does it say diferences or derivatives or something else.Quote:

y=-5(x-2)squared+3
im going to assume that by difference you mean derivative.
1st derivative: -10(x - 2) via:
d/dx of z^n = n*z^(n-1)
i used z=(x-2) and n=2
the 3 gets dropped because the slope of a constant is 0.
simplify to y' = -10x + 20
the 2nd derivative is y''=-10
via the slope of y' is always -10.
hope that helps
