Answer 1

Answer:

See explanation

Step-by-step explanation:

y=g(x) represents the number of bread loaves Sonia bakes per hour, where x is the number of hours she works;

z=f(y) represents the amount of money Sonia earns per loaf, where y is the number of loaves she makes,

so

z=f(g(x)) represents the amount of money Sonia earns per loaf, where x is the number of hours she works.

Now

$y=g(x)=\sqrt{2x^3}\\ \\z=f(y)=9y^2+1,$

so

$z=f(g(x))=9(g(x))^2+1=9(\sqrt{2x^3})^2+1=9\cdot (2x^3)+1=18x^3+1$
