I'm so confused i feel like i have no idea what this all is about! can someone please help me out, and explain how to do this problem? Thank you sooooo much!
If it says to evaluate (f)x for f(10), all it's saying is to plug "10" in wherever "x" appears. So, for this example, you plug "10" in and you get (10)^2 + 1, which is 100 + 1, which is 101. There's your answer.

The answer is f(10)= 10^2 + 1 = 100+1 =101 :)
f(10) = 10^2 + 1
= 100 + 1
= 101 answer//
It's another way of saying "what's the value of f(x) when x = 10?"
10*10 + 1 = 101 <<<
oh that is so easy
f((10)--> means that for every vale of x, you sub in 10
therefore f(10)=(10)^2 +1
and simplify
f(10)=10^2+1
=100+1
=101
f(x) = x² + 1
If you want to find f(10) then substitute 10 for x in the original equation. So you'll get f(10) = 10² + 1 = 101
QED
f(x) = x² + 1
f(10) = (10)² + 1
f(10) = 100 + 1 = 101
