Which table represents the graph of a logarithmic function in the form y=log x when b>1

Two years ago a man was six times as old as his daughter. in 18 years he will be twice as old as his daughter. determine their present ages.

Which best describes the function on the graph? direct variation; k = −2 direct variation; k = -1/2 inverse variation; k = −2 inverse variation; k = -1/2

Y+ 2/y is it a polynomial in one variable or not? and if so, why?
