Question

Evaluate f(x) = x 2 + 1 for f(10).
Answers can be:
1. 2√2
2. 101
3. 21

Answer 1

2. 101

You evaluate it using rules.

f(x)=x2+1 for 100 f(10)

so basically you take what x equals on both sides. for usually means apply. so apply what you know. rules properties or give aways.

f(x)=x2+1 for f(10)=101

Answer 2

If we have f(x) and f(10), then we say that x=10. Basically, whatever is in the brackets, we replace “x” with that. Since the brackets say “10,” our x would be replaced with 10.

So:

f=10*2+1=20+1=21
