- 1. • Last week – Defining Functions • Did you complete the Lesson 1 Quiz? January 21st – Semester 1 Closes!!!! Housekeeping
- 2. Unit 1: Lesson 2 Evaluating Functions
- 3. Evaluating a function is similar to evaluating an expression Examples: Evaluate 8 + v for v = 8. Evaluate 49 − 𝑦2 for y = 5
- 8. Important Rules to remember: Exponents – Squaring a negative Adding and Subtracting Integers Order of Operations
- 13. Use the following function rule to find h(-5). g(x) = 6 – (-5)
- 14. Use the following function rule to find g(-4). g(x) = -3 + x
- 16. Use the following function rule to find f(-10). f(x) = −2𝑥 5 + 𝑥
- 17. Use the following function rule to find f(4). f(x) = −𝑥 + −2 − 𝑥 ÷ 𝑥
- 18. Use the following function rule to find f(3). f(x) = 9 ÷ 𝑥2 + 2 − 2𝑥
