1.) (xy)^(-2/3) = x^(-2/3) y^(-2/3) = x^(-4/3)^(1/2) * 1/y^(2/3) = ... you figure it out.
2.) Exponential function
Intercept: set x = 0 and solve for y = f(x)
y = lim{x→∞} f(x) = ... lower bound of range
y = lim{x→-∞} f(x) = ... upper bound of range (cannot be reached)
Domain: |R (-∞,∞)
Asymptote: upper bound of range
3.) This equation is factorable. Let y = tan(x) if you need to, then replace it after factoring with tan(x) and solve for both factors = 0.
