A scientist is studying the growth of a particular species of plant. He writes the following equation to show the height of the plant f(n), in cm, after n days.

f(n) = 8(1.05)n

Part A: When the scientist concluded his study, the height of the plant was approximately 11.26 cm. What is a reasonable domain to plot the growth function? (4 points)

anonymous · Answer

so is it 11.26 = 8(1.05)^n? and I work backwards to find n?

undeadknight26 · Answer

this is what you need to do: plug in numbers and see if its right:
11.26 = 8(1.05)^3
try this one and see...

then try this one:
11.26 = 8(1.05)^7
this is your answer.
