Operations with Functions
Let f(x) = -3x^1/3 + 4x^1/2 and g(x) = 5x^1/3 + 4x^1/2 Preform the indicated operation and state the domain.
1. f(x) + g(x)
2. f(x) – g(x)
Let f(x) = 4x^2/3 and g(x) = 5x^1/2 Preform the indicated operation and state the domain.
3. f(x) * g(x)
4. f(x) / g(x)
Let f(x) = 3x + 2, g(x) = -x^2 and h(x) = x – 2 / 5 Find the indicated value.
5. f(g(-3))
6. h(g(5))
Let f(x) = 3x^-1, g(x) – 2x – 7, and h(x) = x + 4 / 3 Preform the indicated operation and state the domain.
7. f(g(x))
8. g(f(x))
