Question

A) Complete the table of values for y = x^2 - 4x​

Answer 1

Step-by-step explanation:

The given function is

$y = {x}^{2} - 4x$

To complete table of values for this function, we need to substitute x-values and solve for corresponding y-values.

When x=-1,

$y = ( { - 1)}^{2} - 4( - 1)$

$y = 1 + 4 = 5$

When x=0,

$y = ( { 0)}^{2} - 4( 0) = 0$

When x=1,

$y = ( { 1)}^{2} - 4( 1) = 1 - 4 = - 3$

The table is shown in the attachment.
