    1. If f(x) = 3x + 1 and g(x) = 2x − 4, find f[g(2)]. 25 4 zero 1 2. If f(x) = −x − 1 and g(x) = 4x − 1, find f[g(−2)] −10 −9 −13 8 3. If f(x) = x + 3 and g(x) = −4x − 1, find g[f(4)]. 21 −21 19 −19 4. If f(x) = 4x + 1 and g(x) = −x − 2, find (f + g)(−1). −4<==== 4 −6 −8 5. If f(x) = 2x − 2 and g(x) = 3x − 1, find (f − g)(4). 17 −17 5 −5 6. If f(x) = x − 2 and g(x) = −2x − 1, find (f g)(9) 19 −18 zero −19 7. If f(x) = −2x − 4 and g(x) = x + 4, find ()(−8). −3 3 −1 1 8. If f(x) = x − 4 and g(x) = x − 2, find f[g(−6)]. 9 3 −9 −3 9. If h(x) = 3x − 1 and j(x) = −2x, find h[j(2)]. 11 −11 13 −13<==== 10.
