I don't understand these type of problems.. At all. You don't have to answer them all. Just help me out.. Please?
1. If f(x) = 2x − 2 and g(x) = 3x − 1, find (f − g)(4)
2. If f(x) = 1/3x − 2 and g(x) = −2x − 1, find (f • g)(9)
3. If f(x) = 2x + 1 and g(x) = −2x − 3, find (f + g)(−1).
4. If f(x) = 1/2x + 3 and g(x) = −4x − 1, find g[f(4)]
5. If f(x) = x − 4 and g(x) = x − 2, find f[g(−6)]
6. If f(x) = −3x − 3 and g(x) = 2x + 1, find f/g(−2).
7. If r(x) = 3x − 1 and t(x) = −4x − 1, find (r + t)(7)
8. If f(x) = 3x + 1 and g(x) = 2x − 4, find f[g(2)].
Help IS appreciated.
