Identifying Functions

1. Find the output, \(g\), when the input, \(r\), is \(3\).

\(g=-5 r+13\)

2. Find the output, \(b\), when the input, \(a\), is \(6\).

\(b=-1-7 a\)

3. Find the output, \(y\), when the input, \(x\), is \(5\).

\(y=5 x-3\)

4. Find the output, \(k\), when the input, \(t\), is \(-7\).

\(k=10 t-19\)
