In order to find the instantaneous slope of a curve at a given point one needs to find the derivative of the function and evaluate it at that point.
I assume you know how to find the derivative of a polynomial function.
g(x)=x^2+3/x^2-x
g'(x) = 2x + -6/x^3 - 1
To find the slope of the line at point x = 0, find g'(2).
I find the slope to be 2.25

first we take the derivative. you can do this term by term because there are no products. so we get
g'(x) = 2*x - (3*-2)*x^-3 - 1
= 2*x - 6*x^-3 -1
evaluate at x = 2
g'(2) = 2*2 - 6*(1/8) - 1 = 4 - .75 -1 = 2.25

you need to find g'(x) ie : g'(x) = 2x - 6/x^3 - 1,
then the slope g'(2) = 3 - 6/8 = 3 - 3/4 = 9/4.

The answer is -5/2
Let n=numerator
d=denominator
g'=(n'*d-d'*n)/d^2
n'=2x
d'=2x-1
g'=[2x*(x^2-x)-(2x-1)*(x^2+2)]/(x^2-x)^2)
slope for x=2 is
(4*2-3*6)/4=(8-18)/4=-5/2
