Answer:
Option B) The height, in inches, of a typical apple tree
Step-by-step explanation:
Let
x----> the number of years, after the tree was planted
y ---> the height in inches, of a typical golden delicious apple tree
we have
Remember that
The y-intercept is the value of y when the value of x is equal to zero
In this problem
The y-intercept is the height of the tree when it was planted (x=0)
Answer:
21
Step-by-step explanation (note, the suggested way is not the shortest one):
all the details are in the attached picture.
Answer:
The graph in the attached figure
Step-by-step explanation:
we have
This is a exponential function of the form
where
a is the initial value
b is the base
r is the rate
b=1+r
In this problem we have
a=4 ----> initial value (y-intercept)
b=1/2
so
1+r=1/2
r=1/2-1=-1/2
r=-0.5=-50% ----> is negative because is a decrease rate
using a graphing tool
The graph in the attached figure
