Answer:
[tex]k(x)=5+4\sqrt{x}[/tex]
Step-by-step explanation:
Write a function whose k(x) values are 5 more than four times the principal square root of x.
So,
the principal square root of x [tex]=\sqrt{x};[/tex]
four times the principal square root of x [tex]=4\sqrt{x};[/tex]
5 more than four times the principal square root of x [tex]=5+4\sqrt{x};[/tex]
Thus,
[tex]k(x)=5+4\sqrt{x}[/tex]
