What is "if f(x) = 6x – 4?

The function f(x) = 6x - 4 is a linear function, which means that it has a constant rate of change. In this case, the rate of change is 6. This means that for every 1 unit increase in x, the value of f(x) will increase by 6 units.

The function f(x) = 6x - 4 can be graphed as a straight line with a slope of 6 and a y-intercept of -4. The graph will have a positive slope, meaning that it will slope upwards as x increases.

This function can be used to model various real-life situations where there is a constant rate of change, such as calculating the cost of an item that increases by $6 each hour or the distance traveled by a car moving at a constant speed of 6 miles per hour.

Overall, the function f(x) = 6x - 4 is a simple linear function that can be useful for modeling and analyzing situations with a constant rate of change.
