    The average rate of change is given by: \[\frac{f(x_1)-f(x_2)}{x_1-x_2}\]

    Here, \(x_1=3\) and \(x_2=8\)

    |dw:1438834225000:dw| The average rate of change is the inclination of the line passing through the points (x1, f(x1)) and (x2, f(x2))

    You function if \[f(x)=0.01(2)^x\]

    \(f(3)=0.01(2)^3 = 0.08\)

    do the same for \(f(8)\) and calculate the average rate of change: \[\frac{f(3)-f(8)}{3-8}\]

    Identify the domain of the exponential function shown in the following graph: A curve runs just above the x axis through the second quadrant, passes through point 0 comma 1 and continues off screen near 1 comma 12. all real numbers all positive numbers 1 ≤ x ≤ 30 all integers

    So, if i would say that the domain is all positive numbers. Although I'm not 100% sure, since I can't see the graph
