Question

Can some one help me with 4 questions ?(:

Answer 1

it helps if you actually post the questions :)

Answer 2

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) = 10(1.02)n

Part A: When the scientist concluded his study, the height of the plant was approximately 11.04 cm. What is a reasonable domain to plot the growth function?

Part B: What does the y-intercept of the graph of the function f(n) represent?

Part C: What is the average rate of change of the function f(n) from n = 1 to n = 5, and what does it represent?

Answer 3

the formula for average rate of change is \(A(x)=\dfrac{f(x) - f(a) }{x-a}\) so x would be 5 and a would be 1

as fpr b, y intercepts are of the form (0,y). that is, it's the point on the graph where x is 0. (well in this case n is 0)

I can't remember reasonable domains, sorry

Answer 4

thank you!(:
