Radical function and its graph

Instructions
Move around the slider to see what different values for n look like. Then do the following questions on a piece of A4 paper. Do the problems neatly or else you won't get credit.[br][br]1. Sketch the graph for the following. [br] a) n = 2[br] b) n = 3[br] c) n = 4[br] d) n = 5[br][br]2. Why are odd values for n defined for negative real numbers?[br][br]3. Explain what the result is if n is even and x is a negative real number.
