You will be asked to combine functions. In this tutorial you are shown what we mean by combining functions and introduced to a simple example and the notation that you may expect to see.

#### Examples in the video

If f(x) = 2x – 3, g(x) = 3 / x where x ≠ 0 and h(x) = x^{2}

Find:

- fg(x)
- gfh(x)
- fff(x)

# Example 2

#### Examples in the video

If f(x) = e^{2x + 1}, g(x) = 2x – 4 and h(x) = ln x

Find:

- fg(x)
- hf(x)
- fh(x)
