Question

Non linear graphs - complete the table

Answer 1

x | -1 0 1 2 3 4 5

y | 5 0 -3 -4 -3 0 5

Explanation:

The given function is

`y=x^(2) -4x`

We need to find the y-value for
`x=-1`,
`x=1`,
`x=2` and
`x=4`.

For
`x=-1`

`y=(-1)^(2) -4(-1)=1+4=5`

For
`x=1`

`y=1^(2)-4(1)=1-4=-3`

For
`x=2`

`y=2^(2)-4(2)=4-8=-4`

For
`x=4`

`y=4^(2) -4(4)=16-16=0`

Therefore, the complete table would be

x | -1 0 1 2 3 4 5

y | 5 0 -3 -4 -3 0 5
