I need help with these questions.

18. Which of the following function types exhibit the end behavior f (x) -> co as x -> co and (2 points f (x) ->00 as x ->00 ? Select all that apply. power, y = x" ; n is even and greater than zero. reciprocal; y = root, y = 4/x ; n is even and greater than zero. identity; y = x exponential: y =b",b >0 Oabsolute value: y = x| 19. Identify the key characteristics of the parent fifth-root function / (x) =$/x . Include the (4 poin following: domain, range, intervals where the function is increasing, decreasing, or constant, intercepts, whether the function is even, odd, or neither, whether the function is continuous or discontinuous, asymptotes, and end behavior. 20. What transformations produce the graph of g(x) - - 8x| from the graph of the parent function (2 points) f (x) = x ? Select all that apply. " horizontal stretch by a factor of 8 horizontal compression by a factor of S I vertical stretch by a factor of S "vertical compression by a factor of 8 reflection over the y-axis reflection over the x-axis
