Sean:

f(x)=xf\left(x\right)=\sqrt[]{x} , g(x)=x2−1g\left(x\right)=x^2-1 , h(x)=x+1h\left(x\right)=x+1

determine:

(g o f)(x)\left(g\ o\ f\right)\left(x\right)

(g o f)(x)=x−1\left(g\ o\ f\right)\left(x\right)=x-1

(g o f)(x)=x+3\left(g\ o\ f\right)\left(x\right)=x+3

(g o f)(x)=−x+2\left(g\ o\ f\right)\left(x\right)=-x+2

(g o f)(x)=x−4\left(g\ o\ f\right)\left(x\right)=x-4

(g o f)(x)=x\left(g\ o\ f\right)\left(x\right)=x
