How do you find the value of f(3) if f(x) is given as 2x + 3?

To find the value of f(3), we first need to understand the function f(x) which is defined as:

f(x) = 2x + 3

Now, to calculate f(3), we will substitute the value of x with 3:

f(3) = 2(3) + 3

When we carry out the multiplication:

f(3) = 6 + 3

Now, we add the two values:

f(3) = 9

Therefore, the value of f(3) is 9.
