Understanding Function Notation: Finding f(4)

In the given function f(x) = 2x + 3, we have to find f(4).

By substituting x = 4 in the function, we get: f(4) = 2(4) + 3 f(4) = 8 + 3 f(4) = 11

So, the value of f(4) in the function f(x) = 2x + 3 is 11.

Remember, when you see f(4), it means you need to substitute 4 in place of x in the function and perform the operations to find the value.
