Question

Using Mathematica, Find F's tangent line at a fixed point ( I already defined f(x) as (2x^2+32x)/(-x^3)... i just cannot for the life of me figure out the correct format

Answer 1

f[x_]:=(function)
f'[x]=(derivative)
f'[x1]=(slope of the function at that point]
Tangent line eqn= y-y1=m(x-x1)
m=f'[x1]
point (y1,x1)
