Define $G$:$RR$ by the rule $G(x)=2-5x$ for each real number $x.$

Is $G$ a one$-$to$-$one correspondence? If yes, choose the answer that correctly describes the inverse $G^{-1},$ otherwitue, choose the answer that sars wi$-$

$G$ is a one$-$to$-$one correspondence. The inverse function is $G^{-1}(x)=\frac{5-x}{2}$

$G$ is a one$-$to$-$one correspondence. The inverse function is $G^{-1}(x)=\frac{2-x}{5}$

$G$ is a one$-$to$-$one correspondence. The inverse function is $G^{-1}(x)=25x.$

$G$ is a one$-$to$-$one correspondence. The inverse function is $G^{-1}(x)=2-5x.$

G is not a one$-$to$-$one correspondence.
