Answer:
The name of the function is linear function.
Explanation:
A linear function is the function representing a straight line.
A linear function is used to define the relationship between a dependent variable and independent variable.
The general form of a linear function is:
y = m·x + c
Here,
y = dependent variable
x = independent variable
m = slope
c = intercept
The function provided is:
f (x) = 4·x - 2
The above function is similar to the linear function's general form.
The slope of the provided function is 4 and the intercept is -2.
Thus, the name of the function is linear function.
