Mathematics Investigation QUESTION 1 WHAT ARE THE-th TERM OF AN ARITHMETIC, QUADRATIC AND GEOMETRIC PROGRESSIONS? 1.1 1.1.1 1.1.2 1.2.1 f(x)=x+3 is given. Define the concept function and give conditions which make relation a function. List any six pairs of coordinates from the relation. 1.1.3 Represent the domain and range of your answer in 1.1.1 in the set builder notation. NB: For all number patterns we do in Mathematics, we find our domain being from only elements of Natural numbers N, and the pattern is the range denoted by f(n)=T.. 1.2 Consider the linear graph g sketched below where n is natural numbers.: T NSC-Grade 12 - (1:4) -(2:4) - (3:4) NW/FEB 2022 - (n; T.) What is the domain and range of g? 1.2.2 Why is it reasonable to regard g as g(n)=T? (1) (1) (2) (2) (1) 3
