Since y = 3x + 1 describes a function, rewrite the equation using function notation.
Choose the correct answer.
O A. f(x) = 1x + 3
O B. f(x) = 3x + 1
O C. f(x) = 3y + 1
O D. f(x) = 3x - 1
The correct answer is:
B. f(x) = 3x + 1
To rewrite the equation using function notation, we need to replace y with f(x).
The correct answer is:
B. f(x) = 3x + 1
To rewrite the equation using function notation, we need to replace "y" with "f(x)" since we are using function notation.
The correct answer is B. f(x) = 3x + 1.
Explanation: In function notation, the letter "f" represents the name of the function and "(x)" indicates that the function is dependent on the variable "x". Therefore, "f(x)" is equivalent to "y" in the original equation. By substituting "y" with "f(x)", we get the equation f(x) = 3x + 1.
