Question

Which of the following is the value of f(3) in the function below? f(x)=2x-1

Answer 1

F(3) = 2 * 3 - 1, which is 6 - 1 equaling 5.

Explanation:

3 times 2 is six since you have to follow PEMDAS (Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction). Multiplication is before Subtraction, and that is why we multiply 2 and 3 first, since 3 replaces the variable x. After multiplying 2 and 3 to get 6, subtract by 1 to get 5.

Answer: 5
