Virtual Nerd's patent-pending tutorial system provides in-context information, hints, and links to supporting tutorials, synchronized with videos, each 3 to 7 minutes long. $$f(b) = 3(32) + 5 = 32$$ The two points of a secant line are denoted by: (x 1, y 1) and (x 2, y 2) and t is the total time (number of years. To find the correct value of that answers this question, it suffices to examine the line with slope through and find the point among those given that is closest to the line. Then apply the standard rate of change formula . In a function it determines the slope of the secant line between the two points. From the first point, let a = 4, and f (a) = 8. 8.8- Rate of Change in Exponential and Logarithmic Functions. Now that average rate of change was 13.5 gallons per minute. Thus, $$$\frac{f(b)-f(a)}{b-a}=\frac{\color{red}{\left(3\right)}^{2}-\left(\color{red}{1}^{2}\right)}{3-\left(1\right)}=4$$$.
