How does the graph of g(x) = 3x – 2 compare to the graph of f(x) = 3x?
Graphs are either compared on the basis of the slope or their intercept.
Answer: The graph of both g(x) and f(x) have the same slope, i.e., similar inclination from either axis, but the only difference is in the intercept.
A line with no intercept value always passes through the origin.
Comparing this slope-intercept equation with the g (x) = 3x - 2 and f (x) = 3x, we get:
For g(x): m = 3 , c = -2
For, f (x): m = 3 , c = 0
