Find the derivative of the function f(x) = x^8+ 5x³ - 6x +9

How can you tell when x and y are not directly proportional?

Which of the following describes the symmetry of the graph of y = x3?

The graph of the the function f(x) is given below. find [tex]\lim_{x \to 0\zero} f(x)[/tex] [tex]\lim_{x \to 1+\oneplus} f(x)[/tex] [tex]\lim_{x \to 0-\zeroneg} f(x)[/tex]
