I'm having difficulty figuring this out conceptually. Can you elaborate on these so that I can learn from them? #2 is at the point (0, 1)

Pick two (different) polynomials f(), g(2) of degree 2 and find lim 9(2) Find the equation of the tangent line to the curve y +25 - 1 + 3ry at the point (0, 3) Pick a positive integer a and consider the function / (x) = " a Find S'(r) and f" (x). b) Find all vertical and horizontal asymptotes of /(r). e) Find all intervals where f (r) is increasing/ decreasing. d) Find all intervals where f(r) is concave up/ down
