Step-by-step 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:
[tex]f(x) =\left \{ {{2x + 1\ -1 < x < 3} \atop {4x + 7, x \ge 3}} \right.[/tex]
To calculate f(2), we make use of:
[tex]f(x) =2x + 1[/tex] [tex]-1 < x < 3[/tex]
Because 2 is within [tex]-1 < x < 3[/tex]
So:
[tex]f(2) = 2 * 2 + 1 =5[/tex]
Similarly, to calculate f(3)
We make use of
[tex]f(x) = 4x + 7[/tex]
Because 3 is within [tex]x\ge 3[/tex]
So:
[tex]f(3) = 4 * 3 + 7 =19[/tex]
