Explanation:

The question is incomplete, as the function is not given. A little explanation to assist you is as follows;

From the attached image, one can sense that the function is a piece-wise function.

Now, assume the function is as follows:

`f(x) =\left \{ {{2x + 1\ -1 < x < 3} \atop {4x + 7, x \ge 3}} \right.`

To calculate f(2), we make use of:

`f(x) =2x + 1`
`-1 < x < 3`

Because 2 is within
`-1 < x < 3`

So:

`f(2) = 2 * 2 + 1 =5`

Similarly, to calculate f(3)

We make use of

`f(x) = 4x + 7`

Because 3 is within
`x\ge 3`

So:

`f(3) = 4 * 3 + 7 =19`
