Q16 of 118 Page 3

Let f and g be two functions given by
f = {(2, 4), (5, 6), (8, -1), (10, -3)} and g = {(2, 5), (7, 1), (8, 4), (10, 13), (11, -5)}.

Find the domain of f + g.

D(f) = {2, 5, 8, 10}

D(g) = {2, 7, 8, 10, 11}

Therefore, D(f+g) = {2, 8, 10}

Write the domain and range of function f(x) given by

Let A and B be two sets such that n(A) = p and n(B) = q, write the number of functions from A to B.

Find the set of values of x for which the functions f(x) = 3x² – 1 and g(x) = 3 + x are equal.
