Question

How do you evaluate `h(-10)` given `h(n)=n+4`?

Answer 1

`h(-10)=-6`

Explanation:

Given equation is `h(n)=n+4`

This means that for whatever of `n` substituted (`h(n)`), `n` must be replaced as such.

For example, if we say `n=m`, then we'll write that `h(m)=m+4` where `m+4 in RR`

As such, now we will substitute `n=-10`, so `h(-10)=-10+4`

The rest is up to OP.
