Answer 1

You are seeing \(x\) everywhere..

Just replace that \(x\) by 3 in first case and \(-3\) in second case.. :)

Answer 2

Is the first one 5

Answer 3

\[f(x) = x+2 \implies f(3) = (3) + 2 = ??\]

Answer 4

Yep..

Answer 5

Try second on your own..

Answer 6

Give a try, put \(x=-3\) there..

Answer 7

12?

Ac ually -10?

Answer 10

I mean show me.

Answer 11

Sure??

Answer 12

\[f(-3) = -4(-3) -2 = ??\]

Answer 13

F(-3)=-4(-3)-2=
12-2=10

Answer 14

Good enough to get a medal from me.. :)

Good..
