What is the y-intercept of the function f(x) = 4 – 5x?

The y-intercept of a function is the point where the graph of the function crosses the y-axis. To find the y-intercept, we need to set the value of x to 0 and then solve for f(x).

For the function f(x) = 4 – 5x, we substitute x with 0:

f(0) = 4 - 5(0) = 4 - 0 = 4

This means that the y-intercept is the point (0, 4). Therefore, when the function f(x) = 4 – 5x is graphed, it crosses the y-axis at the point (0, 4).
