Question

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

Answer 1

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.

Answer 2

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.
