Are you ready for the Skills Check?

4. State the Domain and Range

5. Are these Functions? If no, WHY NOT??
Input
Output -2 2 1 4 5 6
YES NO

6. f(-2) = (-2)2 – 2(-2) + 3 f(-2) = 4 + 4 + 3 f(-2) = 11
Evaluating a function
f(x) = x2 – 2x + 3 when x = -2
f(-2) = (-2)2 – 2(-2) + 3
f(-2) =
f(-2) = 11

7. Simplify the following expressions
4(x – 3) + 2x – 7
-2(2x + 1) – 3(5x – 2)
3x2(x3 – 2x2 + 5x +1)
