Answer:

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 
four times the principal square root of x 
5 more than four times the principal square root of x 
Thus,

Answer:9
Step-by-step explanation:
Answer:
4
Step-by-step explanation:
I'm pretty sure theres a graph to this so....
The given parabolic graph of quadratic function
To find:What is F(6) for the quadratic function
Solution:We have given graph of quadratic function
there is a different value for Y and a different value for X
For f(6)
here X=6, need to find graph of quadratic function
X=6
f(6)=4
Y=4
Your welcome :)
