The graph of $f\left(x\right)=9^x$`f`(`x`)=9`x` is given below. Another exponential function, $g\left(x\right)$`g`(`x`), is increasing at exactly the same rate as $f\left(x\right)$`f`(`x`), but has a different $y$`y`-intercept. Which of the following could be the equation of function $g\left(x\right)$`g`(`x`)?
