Given:

Equation of line is,

[tex]g(x)=-20\sqrt[]{x}[/tex]

The slope of the secant line between x =a and x= b is calculated as,

[tex]\begin{gathered} m=\frac{f(b)-f(a)}{b-a} \\ m=\frac{f(3)-f(2)}{3-2} \\ m=\frac{-20\sqrt[]{3}-(-20\sqrt[]{2})}{1} \\ m=-20\sqrt[]{3}+20\sqrt[]{2} \\ m=20(\sqrt[]{2}-\sqrt[]{3}) \\ m=-6.36 \end{gathered}[/tex]

Answer: slope of the secant line is m = -6.36
