Please help me with task 2
BIG idea: Equivalence
You can represent any function in an unlimited number of ways, where all representations have the same domain and
the same pairing of inputs with outputs.
Task 2
A sequence is a function with domain the natural numbers 1, 2, 3, .... Using function notation, you can write
the sequence an = ª₁ + (n − 1)d as a (n) = a₁ + (n − 1)d and the sequence
an= a₁7¹¹ as a (n) = α₁¹-¹.
