The line g(x) has a greater rate of change compared to f(x), as evidenced by their respective slopes. g(x) has a slope of
\((2)/(3)\), which is larger than f(x)'s slope of
\((1)/(4)\).

To determine which line, f(x) or g(x), has a greater rate of change, we can compare the slopes of the two lines.

The slope of a line passing through two points
\((x_1, y_1)\) and \((x_2, y_2)\) is given by the formula:


\[ \text{Slope} = (y_2 - y_1)/(x_2 - x_1) \]

Let's calculate the slopes for both lines:

For line f(x), passing through points (-4,-2), (0,-1), (4,0):


\[ \text{Slope}_(f) = (-1 - (-2))/(0 - (-4)) = (1)/(4) \]

For line g(x), passing through points (-3,-4), (0,-2), (3,0), (6,2):


\[ \text{Slope}_(g) = (-2 - (-4))/(0 - (-3)) = (2)/(3) \]

Comparing the slopes, we find that g(x) has a greater rate of change, as its slope (
\((2)/(3)\)) is larger than the slope of f(x) (
\((1)/(4)\)).
