Find each value of f(x)=
f(x) =
1. f(4); all this means is, that you substitute 4 for x in the above expression and find out it's numerical value (evaluate):
f(4) =
:
f(4) =
:
f(4) = = 2
:
:
2. f(-8); Substitute -8 for x in the given expression
f(-8) =
f(-8) = = = -22
:
How about this, did it help you understand this? Any questions?
