find the average rate of change of the function $f(x)=sqrt{x}+1$ on the interval $4leq xleq9$. recall that the coordinates for the start of the interval are $(4,3)$. what are the coordinates for the end of the interval? (9,4) (9,3) (9,82) done

Answer

Explanation:

Step1: Substitute end - point value of x.

We have the function $f(x)=\sqrt{x}+1$. When $x = 9$, we calculate $f(9)=\sqrt{9}+1$. Since $\sqrt{9}=3$, then $f(9)=3 + 1=4$. The x - value for the end of the interval is 9 and the y - value (function value) is 4.

Answer:

A. $(9,4)$
