Answer:
Graph B
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
a=2 ----> the y-intercept
b=3
so
1+r=3 -----> r=3-1=2 -----> r=200%
so
The y-intercept of the graph is equal to 2
As x increases the value of f(x) increases
therefore
Graph B
Answer:
Henry walks 7 kilometres from school to library
Step-by-step explanation:
Given:
1 unit = 1 Kilometre
To Find:
The distance between the library and the school
Solution:
The map below shows that Henry has walked from
-2 coordinate in the x axis to coordinate 5 along the same x axis
So he has walked a total of 7 units
Since we know that 1 unit = 1 Kilometre,
7 units will be
=> 7 x 1
=> 7 Kilometres
