Question

How do you graph `y = 4 - abs(x-2)`?

Answer 1

Determine several points by substituting positive and negative values for `x`. Plot the points and draw lines through the points. The graph should have the shape of a an upside-down V.

Explanation:

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

Determine several points by substituting positive and negative values for `x`.

`x=-3,` `y=-1`
`x=-2,` `y=0`
`x=-1,` `y=1`
`x=0,` `y=2`
`x=1,` `y=3`
`x=2,` `y=4`

Plot the points and draw lines through the points. The graph should have the shape of a an upside-down V.
