Students observing a caterpillar crawl on a tree noticed that the caterpillar crawled upwards ( frac{3}{8} ) of an inch every minute. The caterpillar was already 4.5 feet off the ground when the students began observing. Which function represents the height of the caterpillar above the ground in inches after ( x ) minutes? ( f(x)=frac{3}{8} x+4.5 ) ( f(x)=4.5 x+frac{3}{8} ) ( f(x)=54 x+frac{3}{8} ) ( f(x)=frac{3}{8} x+54 )

Step 1
There are 12 inches in a foot, so 4.5 feet is 4.5 * 12 = 54 inches. Show more…

The height of a certain plant, in inches, after $t$ weeks is $$f(t)=\frac{1}{.05+e^{-.4 t}}$$ The graph of $f(t)$ resembles the graph in Fig. 4. Calculate the rate of growth of the plant after 7 weeks.

The height of Quinn's beanstalk decreases by 50% per day when Quinn stopped feeding it. The initial height of the beanstalk is 20 inches. Write a function f that determines the height of Quinn's beanstalk (in inches) as a function of the number of days, denoted by x, since Quinn stopped feeding the beanstalk: f(x) Plot the points (0, f(0)), (1, f(1)), (2, f(2)), and (3, f(3)) on the graph below: The function f(x) is an exponential function.
