^{2}-1 and g(x)=x

^{2}+2. Find an expressions for f(g(x)).

Is the answer 3x

^{4}+5x

^{2}-2 and if so what working would i show?

Functions f and g are given by f(x)=3x^{2} -1 and g(x)=x^{2}+2. Find an expressions for f(g(x)).

Is the answer 3x^{4}+5x^{2}-2 and if so what working would i show?

Is the answer 3x
