Modeling with Linear Functions · Exercise 4
Graph and interpret applications of slope–intercept form of a linear function.
Cassandra is a botanist who is studying the growth of pea plants under a variety of conditions. One experiment yields the following results. For a seedling starting off at 3 inches the growth rate each week 1.25 inches.
ⓐWrite a height function, H(t), which will give the plant height as a function of time in weeks, t.
ⓑ Estimate the plant height for each of the following amounts of time paying attention to units provided.
ⓒ Her plants will need to be secured to a stick when they reach 12 inches in height. Estimate the time when her samples will need to be secured.
ⓓ Graph the function below. Be sure to show the scale you are using.
