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
