Answer 2

The given function is:

F(x) = 2 / √x + x

This function combines two terms: 2 / √x and x. Let's break it down further:

Term 1: 2 / √x This term represents the division of 2 by the square root of x. The square root of x (√x) denotes the non-negative number that, when multiplied by itself, gives x.

Term 2: x This term simply represents the variable x.

To evaluate the function at a specific value of x, you substitute that value into the function and simplify the expression.

For example, if we want to evaluate F(x) at x = 4:

F(4) = 2 / √4 + 4

Since √4 = 2, we can simplify the expression:

F(4) = 2 / 2 + 4 = 1 + 4 = 5

Therefore, when x = 4, F(x) equals 5.
