Given:
A function represents a line is given below
f(x) = 3x - 4
Find:
we have to determine the given line is increasing or decreasing or constant.
Explanation:
we know a function f(x) is increasing if f'(x) > 0
and a function f(x) is is decreasing, if f'(x) < 0.
given f(x) = 3x - 4
f'(x) = 3
Therefore, f'(x) > 0.
Therefore, the line is increasing.
