What is the vertical asymptotes of the function f(x)=x-2/x*2-3x-4

The table represents a function f(x). what is f(3)? a.-9 b.-1 c.1 d.9

Use the formulas a = x 2 – y 2, b = 2xy, c = x 2 + y 2 to answer this question. one leg of a right triangle has length 11 and all sides are whole numbers. find the lengths of the other two sides. the other leg = a0 and the hypotenuse = a1
