Answer:

$\boxed {\boxed {\sf 11}}$

Explanation:

We are given the following function and asked to find the output if the input is 3.

f(x)= 2x+5

The input is what is plugged into the function and its variable is x. The output is the result of plugging in the input and its variable is y.

Substitute 3 in for x,

f(3)= 2(3)+5

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. Multiply 2 and 3.

f(3)= 6+5

Add.

f(3)= 11

If the input is 3, then the output is 11.
