For what value of the constant c is the function f continuous on (-0, co)? cx2 + 5x if x = 6 f(x) = if x 2 6 x3 - cx Step 1 Note that f is continuous on (-0, 6) and (6, 0). For the function to be continuous on (-0, 0), we need to ensure that as x approaches 6, the left and right limits match. First we find the left limit. lim f(x) = lim (cx2 +...
