For each function:

i. Represent the function on a mapping diagram, writing down the elements in the range

ii. State whether the function is one-to-one or many-to-one.

a f(x) = 2x + 1 for the domain {x = 1, 2, 3, 4, 5} b g: x x for the domain {x = 1, 4, 9, 16, 25, 36} ch(x) = x for the domain {x = -2, -1, 0, 1, 2} 2 d j: x for the domain {.x = 1, 2, 3, 4, 5} X e k(x) = ex + 3 for the domain {x = -2, -1, 0, 1, 2}
