Algebra 2 EOC Inverses and Radical Functions

Given $f\left(x\right)=-3x+7$  and  $g\left(x\right)=2x^2-8$ , find  $\left(g\circ f\right)\left(x\right)$ .

•  $\left(g\circ f\right)\left(x\right)=-6x^2+31$ 

•  $\left(g\circ f\right)\left(x\right)=-6x^2+24$  
  

•  $\left(g\circ f\right)\left(x\right)=18x^2-84x+90$ 

•  $\left(g\circ f\right)\left(x\right)=9x^2-42x-41$
