Question

Find the output of each function using the input 7

F(x)=5+| 3-x |

Answer 1

The input is 7, so replace x in the equation with 7:

5 + |3-7|

Simplify:

5 +|-4|

The vertical bars mean absolute value, which means if the number is a negative value it becomes a positive value:

5 + 4

Output = 9
