f(x)
X. F(x)
-4

Answer 1

The table for the function f(x) = -3x is completed by multiplying each x value by -3. The result in set notation is { (-4, 12), (1, -3), (2, -6), (3, -9), (6, -18) }.

The student is asked to complete the table for the function f(x) = -3x.

To find the values of f(x) for the given x values, simply multiply each x value by -3.

Applying the function to each x:

For x = -4: f(x) = -3(-4) = 12

For x = 1: f(x) = -3(1) = -3

For x = 2: f(x) = -3(2) = -6

For x = 3: f(x) = -3(3) = -9

For x = 6: f(x) = -3(6) = -18

The completed set in set notation is:

{ (-4, 12), (1, -3), (2, -6), (3, -9), (6, -18) }
