Find the intercepts and the vertical and horizontal asymptotes, and then use them to sketch a graph of the function. Enter the intercepts as points, (a, b). The x-intercept is f(x) = = x+2 x2 -16 The y-intercept is The field below accepts a list of numbers or formulas separated by semicolons (e.g. 2; 4; 6 or x+1; x1). The order of the list does not matter. Vertical asymptotes: x = Horizontal asymptote: y = Q
