Answer:

[tex]f(x) = 12 + \frac34x[/tex]

Step-by-step explanation:

Hello!

Function notation simply means replacing the term y with f(x).

Given the equation: y = 3/4x + 12

  • f(x) = 3/4x + 12

The equation in function notation is [tex]f(x) = \frac34 x + 12[/tex].

What does f(x) mean?

The meaning of f is just the name of the function. x is the variable being used in the function. Therefore, it can also be written as g(y), s(d), or e(f), as long as the variable inside the parenthesis exists in the equation.

Suppose you see a number in the spot for the variable. In that case, you are replacing the variable in that equation to evaluate when the x-value is that number.

Ex:

  • f(x) = 2x
  • f(1) = 2(1)
  • f(1) = 2

Interpreting this will tell you the value of y when x is 1. The y-value is 2.
