Assignment A- Composition of Functions

In the composition of functions, the output of g(x) is used for the input of f(x). The composition of function is f(g(x)). This mean can be said as f of g of x.  In the desmos activity we have f(x)=3x+2 and g(x)=x^2. In this example I will change the input to 5.

If we plug in 5 into g(x),  we get g(5)=5^2=25, this would be output and we would plug that in for the input of f(x)=3x+2.

The next step is to plug in the output which is 25 into 3(25)+2=77. The final composition would be f(g(5))=f(25)=77.

Are there other methods in solving functions? Do you find this interesting?
