Question

Think about the function (f(x) = 3 - 2x). What does the notation (f(0)) mean?

A. The output (y-value) when x = 0
B. The input (x-value) when y = 0
C. The slope of the function at x = 0
D. None of the above

Answer 1

In the notation (f(0)), '0' is the input value for 'x'. For f(x) = 3 - 2x, substituting x with 0 gives the y-value where the function intersects the y-axis.

Step-by-step explanation:

The notation (f(0)) refers to the output or the y-value of the function when the input x is equal to 0. In the context of a linear function like f(x) = 3 - 2x, this would mean substituting x with 0 to find the y-intercept of the graph where it crosses the y-axis. The correct answer is A. The output (y-value) when x = 0.
