Question
make a function table for each function. then state the domain and range of the function. example 2 4. $f(x) = 6x - 4$ 5 $f(x) = 5 - 2x$ 6. $f(x) = 7 + 3x$
Step1: Choose x-values
Let's pick x = 0, 1, 2, 3 for simplicity.
Step2: Calculate f(x) for x=0
Substitute x = 0 into \( f(x) = 5 - 2x \): \( f(0) = 5 - 2(0) = 5 \)
Step3: Calculate f(x) for x=1
Substitute x = 1: \( f(1) = 5 - 2(1) = 3 \)
Step4: Calculate f(x) for x=2
Substitute x = 2: \( f(2) = 5 - 2(2) = 1 \)
Step5: Calculate f(x) for x=3
Substitute x = 3: \( f(3) = 5 - 2(3) = -1 \)
Step6: Determine Domain
For linear functions \( f(x) = mx + b \), the domain is all real numbers (\( \mathbb{R} \)) since there are no restrictions on x.
Step7: Determine Range
Since it's a linear function with \( m
eq 0 \), the range is also all real numbers (\( \mathbb{R} \)) as y can take any real value.
Function Table:
| x | 5 - 2x | f(x) |
|---|---|---|
| 1 | 5 - 2 | 3 |
| 2 | 5 - 4 | 1 |
| 3 | 5 - 6 | -1 |
Domain and Range:
Domain: All real numbers (\( \mathbb{R} \))
Range: All real numbers (\( \mathbb{R} \))
