Question

PLEASE HELP!!! Please help me answer the questions that are circled, I really need help!

Answer 1

Answer:

Here:

Step-by-step explanation:

23. f(x) = $\sqrt{x}$ and g(x) = $x^2-5x$

24. f(x) = $x^2$ and g(x) = $x^3+1$

28. f(x) = $e^x$ and g(x) = $sinx$

29. f(x) = $cosx$ and g(x) = $\sqrt{x}$

Basically, you try to find a function contained inside a function if that makes sense. For example in question 23, g(x) itself is a function =  $x^2-5x$. Same with f(x) = $\sqrt{x}$ . In this case, when we try to fo f(g(x)), we are basically replacing x in the f(x) function by the equation in g(x). Hope this makes sense.
