For the graphed function f(x) = −(5)x − 3 + 2, calculate the average rate of change from x = 4 to x = 6.

graph of f of x equals negative 1 times 5 to the x minus 3 power, plus 2

yeah hold on let me try  to interpret what you wrote

anonymous · Answer

$$f(x)=-5^{x-3}+2$$?

anonymous · Answer

$$f(x)=-1\times 5^{x-3}+2$$

anonymous · Answer

$$\frac{f(6)-f(4)}{6-4}$$ is what we need to compute

anonymous · Answer

$$f(6)=-2\times 5^3+2=-25+2=-23$$

anonymous · Answer

oh not that is wrong 
$$f(3)=-1\times 5^3+2=-125+2=-123$$ thats better

anonymous · Answer

$$f(4)=-1\times5^1+2=-5+2=-3$$

anonymous · Answer

$$f(6)-f(3)=-123-(-3)=-120$$ divide by 2 get $-60$
