· We are given that f (x)=x² We have to find g (x) Since, we are given that g (3)=1 Hence, we will proceed by the options 1 g (x)= at x=3 g (x)=1/9 Hence, this option is incorrect 2 g (xExample 5 We now look at the functions f(x) = and g(x) = 4 – x 2 and find the domain and range of their composite functions We obviously have to limit the values under the squareroot sign to non negative numbers only Therefore the composite function f(g(x)) = can only take the positive values that we get from the function g(x) = 4 – x 2You can put this solution on YOUR website!
