The piece wise function f(x) has a dual identity so to speak. It is either OR . It depends on what the x value is. Note: f(x) cannot be both at the same time.
If , then as the first line shows in the piecewise function.
OR
If , then as the second line shows in the piecewise function.
The value x = 7 makes a true inequality. This value is larger than 4. So we will use as our function
Plug in x = 7. Use the order of operations PEMDAS to simplify Replace every x with 7
