Question 109046: For f(x) = 2x – 11, find f(2)
Answer by bucky(2189)   (Show Source):
You can put this solution on YOUR website! All f(2) means is that you go to the given f(x) and replace every x with 2 and then simplify.
.
So for this problem start with:
.
f(x) = 2x - 11
.
replace every x with 2 to get:
.
f(2) = 2*2 - 11
.
multiply out the right side and simplify it to:
.
f(2) = 4 - 11
.
simplify further by subtracting 11 from 4 to arrive at:
.
f(x) = -7
.
That's the answer ... f(x) is equal to -7
.
Hope this helps you to understand what you do with problems such as these.
