$375\%$ growth.

Growth or decay rate $r=b-1$ where $r$ is a percentage written as a decimal and $b$ is the base of an exponential function of the form $g(x)=a\cdot b^{x}$. Given $g(x)=7(4.75)^{x}$ $\implies b=4.75$ $r=b-1=4.75-1=3.75$ Or $r=3.75\times100 \%=375\% $ $r$ is positive. So, there is $375\%$ growth.
