Rosana is tracking how many customers she can serve in a morning. she listed the number of customers served per hour in the following table:
hour (x) number of customers f(x)
1 3
2 5
3 7
determine if these data represent a linear function or an exponential function, and give the common difference or ratio.
a. this is a linear function because there is a common difference of 2.
b. this is an exponential function because there is a common ratio of 2.
c. this is a linear function because there is a common difference of 3.
d. this is an exponential function because there is a common ratio of 3.

  A. This is a linear function because there is a common difference of 2

Step-by-step explanation:

Differences are ...

The differences of 2 are common, so this is an arithmetic function.

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
