Question

need help:
Consider the function f(x) = x^2-16/x+3. Determine all asymptotes of this function including horizontal, vertical, and oblique (slant).
please check:
What are the discontinuities of the function f(x) = x^2-36/4x+24? --> x can not = -6 correct?
What is the oblique asymptote of the function f(x) = x^2+5x+6/x-4? --> y =x+9 correct?
What are the vertical asymptotes of the function f(x) = 5x+1/x^2+x-6? --> x can not = -2, x = 3 correct?
What are the zeros of the function f(x) = 3x^2-3x-6/3x-6? --> 2 correct?
Consider the function f(x) = x^2+x-12/x-3. Describe the graph of this
