Question

How do you evaluate `w(-4)` given `w(t)=t-5`?

Answer 1

See the entire solution process below:

Explanation:

To evaluate `w(-4)` we need to substitute `color(red)(-4)` for every occurrence of `color(red)(t)` in the function from the problem:

`w(color(red)(t)) = color(red)(t) - 5` becomes:

`w(color(red)(-4)) = color(red)(-4) - 5`

`w(color(red)(-4)) = -9`
