Question 1 (2 points) Consider the function f(x)= 5(x-4) x+2x- 8 (a) To use a limit and find its horizontal asymptote what must be done first? (b) Find the horizontal asymptote as x co using your limit. Question 2 (2 points) For the function f(x)=5+5x-x, find the local extrema. Then, classify the local extrema using the second derivative test. Question 3 (2 points) The function f(x)-x-3x+x+2 is concave up on which interval?
