What is """if f(x) = 6x – 4"?

The expression `f(x) = 6x – 4` defines a [linear%20function](https://www.wikiwhat.page/kavramlar/linear%20function).

*   **Definition:** It states that for any input `x`, the function `f` will output a value obtained by multiplying `x` by 6 and then subtracting 4.

*   **Evaluation:** To evaluate the function for a specific value of `x`, simply substitute that value into the expression. For example, `f(2) = 6(2) - 4 = 12 - 4 = 8`.

*   **Slope-Intercept Form:** The function is in [slope-intercept%20form](https://www.wikiwhat.page/kavramlar/slope-intercept%20form) (y = mx + b), where:
    *   `m = 6` is the [slope](https://www.wikiwhat.page/kavramlar/slope) (rate of change) of the line.
    *   `b = -4` is the y-[intercept](https://www.wikiwhat.page/kavramlar/intercept) (the point where the line crosses the y-axis).

*   **Graph:** The graph of this function is a straight line.

*   **Domain and Range:** The [domain](https://www.wikiwhat.page/kavramlar/domain) and [range](https://www.wikiwhat.page/kavramlar/range) are both all real numbers.
