    Use a graph of f or some other method to determine what, if any, value to assign to f(a) to make f continuous at x = a. HINT [See Example 2.] (If there is no such value, enter NONE.) f(x) = x 2x2 − x ; a = 0

  96. CALC HELP!

    Find an equation of the tangent line to the graph of y= x+ (4/x) at the point (4,5). I can't figure out the answer to this. It's supposed to be y=3/4x +2 but I can't get that.
