We have a function f(x):
[tex]f(x)=2^{(x+2)}+1[/tex]We have to calculate the average rate change for x=-1 to x=0.
We can express an average rate of change as:
[tex]\frac{\Delta f(x)}{\Delta x}=\frac{f(x_2)-f(x_1)}{x_2-x_1}[/tex]In this case, we have:
[tex]\frac{\Delta f(x)}{\Delta x}=\frac{f(x_2)-f(x_1)}{x_2-x_1}=\frac{f(0)-f(-1)}{0-(-1)}=\frac{5-2}{0+1}=3[/tex]The average rate of change is 3 in this interval.
