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

f(x)=3x² -1;g(x)=3+x

For

3x² -1=3+x

3x² -x-4=0

(3x-4)(x+1)=0

3x-4=0 orx+1=0

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.

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.

Let f and g be two real functions given by
