Step-by-step explanation:
The given function is
[tex]y = {x}^{2} - 4x[/tex]
To complete table of values for this function, we need to substitute x-values and solve for corresponding y-values.
When x=-1,
[tex]y = ( { - 1)}^{2} - 4( - 1)[/tex]
[tex]y = 1 + 4 = 5[/tex]
When x=0,
[tex]y = ( { 0)}^{2} - 4( 0) = 0[/tex]
When x=1,
[tex]y = ( { 1)}^{2} - 4( 1) = 1 - 4 = - 3[/tex]
The table is shown in the attachment.

Answer:
Step-by-step explanation:
y = x² - 4x
x = -1 y = 5
x = 0 y = 0
x = 1 y = -3
x = 2 y = - 4
x = 3 y = - 3
x = 4 y = 0
x = 5 y = 5
Hope this helps.
