Question

Use a graphing calculator to graph and then select the response which is true. (5 points)

f increases without bound

f has no tangent line

f has a horizontal tangent line

none of these responses

Answer 1

f increases without bound: y= x^3

f = 3 or any constant: f is a flat horizontal line

f has no tangent line: a discontinuous function such as y =[x] a smallest or lowest integer function. which is just a set of points, none next to another. or y = all natural numbers = {x| x is not a fraction or irrational number or negative or zero)

none of the above: y=-x^3 which decreases without bound
