Given the function:

f(x) = | x |

Find f (8)

Solution:

In order to find  f(8), we simply need to substitute 8 to the value of x. Notice that x is enclosed with an absolute value sign, which means that the value of the number enclosed with that sign is equal to its positive value. Hence, if a negative number is enclosed with the absolute value sign, the answer will be positive.

f(x) = | x |

f(8) = | 8 |

f(8)= 8

Final answer:

f(8)= 8
