2. S.L.O.T g=6x , solve for x Day 1 Monday February 26, 2018
Objective: I can evaluate a function with a given value.
S.L.O.T
g=6x , solve for x
U= x-k , solve for x

3. Evaluate
Solve
Plug in

4. Evaluate p+2q+ 3r given p = 2 q = 4, r = 6
=2+ 2(4) + 3(6) =
=28

5. Example : Evaluate 3c + 5 if c = 5 and d = 1 4d Solution := 4
= 20
= 5

6. Which do you prefer to write?
Function Notation
The f is the name of the function machine and the value inside the parentheses is the input. The expression to the right of the equal sign shows what the machine does to the input. 25
Which do you prefer to write?
Evaluate f when x = 25? OR 5

7. Example If f(x) = 2x + 3, find f(5).
When evaluating, do not write f(x)!
You want x=5 since f(x) was changed to f(5)
You wanted to find f(5). So the complete final answer includes f(5) not f(x)

8. Solving
g(x)=2x-1 g(0) g(-1) g(2)

9. Substitute and Evaluate
Evaluating
Substitute and Evaluate
The input (or x) is 3.
