If f(3) = 3^x and g(x) = 7^x then the graph of g(x) will be — the graph of f(x) when x<0.

Allushta [10]

Using the given exponential functions, it is found that the graph of g(x) will be less than than the graph of f(x) when x < 0.

<h3>What are the exponential functions?</h3>

The given exponential functions, f(x) and g(x), are respectively given by:

$f(x) = 3^x$

$g(x) = 7^x$

When x < 0, one possible value is x = -1, hence evaluating the functions at these values:

$f(-1) = 3^{-1} = \frac{1}{3}$

$g(-1) = 7^{-1} = \frac{1}{7}$

$\frac{1}{3} > \frac{1}{7}$ , hence, the graph of g(x) will be less than than the graph of f(x) when x < 0.
