Question

A relation 'f' is defined by f(x) =x^2 - 2 where x{-2,-1,0,3} list the elements of f

Answer 1

Range = x = {-2, -1, 0, 3}

f(x) = x² - 2

Elements of the relation 'f' :

==> { (-2, f(-2)) , (-1, f(-1)) , (0, f(0)) , (3, f(3)) }

==> { (-2, 2) , (-1, -1) , (0, -2) , (3, 7) }

Elements of 'f' are:

(-2, 2)

(-1, -1)

(0, -2)

(3, 7)
