Question

Make a table of values for the function y=-3x. complete the table x -4,-3,0,3,4

Answer 1

The function is y = -3x

The values of x are -4, -3, 0, 3, 4

We need to substitute x by each given value to find the corresponding values of y

`\begin{gathered} \because x=-4 \\ \therefore y=-3(-4) \\ \therefore y=12 \end{gathered}`

The first number in the column of y is 12

`\begin{gathered} \because x=-3 \\ \therefore y=-3(-3) \\ \therefore y=9 \end{gathered}`

The second number in the column of y is 9

`\begin{gathered} \because x=0 \\ \therefore y=-3(0) \\ \therefore y=0 \end{gathered}`

The 3rd number in the column of y is 0

`\begin{gathered} \because x=3 \\ \therefore y=-3(3) \\ \therefore y=-9 \end{gathered}`

The 4th number in column of
