Answer:
fgh(x)=4[tex]\sqrt{x}[/tex] -14
Step-by-step explanation:
when solving composite fuctions we go from the right to the left
meaning we replace the x in the g function with the entire h function
then replace the x in the f function with the entire new g function
h(x)=[tex]\sqrt{x}[/tex]
g([tex]\sqrt{x}[/tex])=[tex]\sqrt{x}[/tex] -5
f([tex]\sqrt{x}[/tex]-5)=4([tex]\sqrt{x}[/tex] -5)+6
f([tex]\sqrt{x}[/tex]-5)=4[tex]\sqrt{x}[/tex] -20+6
fgh(x)=4[tex]\sqrt{x}[/tex] -14
