You plug the number you have in for 'x' ...and do the operation...and when you are done, if it is a negative number you change it to positive ...

so for 1)

f(x) = |x + 8| f(-11)

plug in -11 for 'x'

f(-11) = |-11 + 8|

Do the operation

f(-11) = |-3|

is that a negative? yes...so change it to a positive number...

f(-11) = 3

Can you do the other 2?
