Which of the following exponential functions goes through the points (1, 12) and (2, 36)? Select one:
a. f(x) = 4(3)−x
b. f(x) = 3(4)−x
c. f(x) = 3(4)x
d. f(x) = 4(3)x

b. f(x) = 3(4)−x

Step-by-step explanation:

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
