2. Solve the following equation for x. 1/x+1-1/3x-1 = 2 3. By first completing the square, find the maximum value of the function f given by f (x) = 16 - 6x x^2, x element of [-4, 4]. Find where the graph of f crosses the coordinate axes, sketch the graph of f and state the range of f. 4. Find all values of x element of R which satisfy the inequality X^3 + 1 > = (x + 1)^2. 5. Find the coordinates of the points of intersection of the straight line x - 2y =0 with the circle x^2 + y^2 = 1/4 6. A function g is given by g(x)=1/x+1, x is not equal to -1. Find and simplify expressions for g(g(x)) and g (1/x).
