Answer:

$k(x)=5+4\sqrt{x}$

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 $=\sqrt{x};$

four times the principal square root of x $=4\sqrt{x};$

5 more than four times the principal square root of x $=5+4\sqrt{x};$

Thus,

$k(x)=5+4\sqrt{x}$
