Consider the given table of values.

Find the equation of the curve in the form $y=a^x$y=ax.

The graph of $f\left(x\right)=9^x$f(x)=9x 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)?
