Answer:

See below.

Step-by-step explanation:

So we have the two functions:

[tex]f(x)=x^2\text{ and } g(x)=x-3[/tex]

And we want to find:

[tex]f(g(x))[/tex]

So, substitute g(x) into f(x):

[tex]f(g(x))=(g(x))^2=(x-3)^2[/tex]

And we're done!

If preferred, we can expand:

[tex]f(g(x))=x^2-6x+9[/tex]
