what is the y - intercept of the function $f(x)=4 - 5x$?\n-5\n-4\n4\n5

Explanation:

Step1: Recall y - intercept formula

The y - intercept of a function (y = f(x)) is found by setting (x = 0).

Step2: Substitute (x = 0) into the function

Given (f(x)=4 - 5x), when (x = 0), we have (f(0)=4-5\times0). Since (5\times0 = 0), then (f(0)=4).

Answer:

C. 4
