Answer:

f(x)=(x+1)^2-2 is the minimum and g(x)=-(x-2)^2+1 is the maximum

Step-by-step explanation:

Looking at the graph, (you should be able to graph this) the parabola for f(x)=(x+1)^2-2 is pointing downwards and stops at the vertex. This vertex is negative which is the lowest point possible which makes it the minimum. The parabola for -(x-2)^2+1 is pointing upwards and stops at the vertex which is the highest point possible which makes it the maximum.

$f(x)=\dfrac{3}{\sqrt{x}}\\\\g(x)=3x+4\\\\\\y=f(g(x))=f(3x+4)=\dfrac{3}{\sqrt{3x+4}}$
