Question

complete the table and then graph the function.
f(x) = 2x
x | f(x)
1 |
4 |
5 |
click to select points on the graph.

Explanation:

Step1: Calculate f(1)

Given the function \( f(x) = 2x \), substitute \( x = 1 \) into the function.
\( f(1) = 2\times1 = 2 \)

Step2: Calculate f(4)

Substitute \( x = 4 \) into the function \( f(x) = 2x \).
\( f(4) = 2\times4 = 8 \)

Step3: Calculate f(5)

Substitute \( x = 5 \) into the function \( f(x) = 2x \).
\( f(5) = 2\times5 = 10 \)

Answer:

For \( x = 1 \), \( f(x) = 2 \); for \( x = 4 \), \( f(x) = 8 \); for \( x = 5 \), \( f(x) = 10 \)
