Evaluate the function k(x) = x+1 for the given values of x. Write exact answers in simplified form. If the function is undefined at the given value of x, use the "Undefined" button. (a)k(5) (b)(-7) (c) k (1) (a)k(-1) (e) k (0) Part 1 of 5 (a) k (5) = Part 2 of 5 (b) k (-7)= Undefined Undefined G (c) k (1) = Undefined Part 4 of 5 (d) k (1) = Undefined Part 5 of 5 (e) k (0) = Undefined G valuate the function h(x) = 5 for the given value of x. Simplify your answer. h(9) = G
