# The point (-12, 4) is on the graph of y = f(x). Find the corresponding point on the graph of y = g(x)? (Refer to below)

##
1) #g(x) = 1/2f(x)#

2) #g(x) = f(x-2)#

3) #g(x) = f(-x)#

4) #g(x) = f(4x)#

5) #g(x) = 4f(x)#

6) #g(x) = -f(x)#

I know the answers for 1, 3, and 5 are (-12, 2), (12, 4), and (-12, 16) respectively, but I don't know how to solve them.

#### Explanation:

#### Answer:

#(-12,2)# #(-10,4)# #(12,4)# #(-3,4)# #(-12,16)# #(-12, -4)#

#### Explanation:

1:

Dividing the function by 2 divides all the y-values by 2 as well. So to get the new point, we will take the y-value (

#4# ) and divide it by 2 to get#2# .Therefore, the new point is

#(-12,2)#

2:

Subtracting 2 from the input of the function makes all of the x-values increase by 2 (in order to compensate for the subtraction). We will need to add 2 to the x-value (

#-12# ) to get#-10# .Therefore, the new point is

#(-10, 4)#

3:

Making the input of the function negative will multiply every x-value by

#-1# . To get the new point, we will take the x-value (#-12# ) and multiply it by#-1# to get#12# .Therefore, the new point is

#(12,4)#

4:

Multiplying the input of the function by 4 makes all of the x-values be

dividedby 4 (in order to compensate for the multiplication). We will need to divide the x-value (#-12# ) by#4# to get#-3# .Therefore, the new point is

#(-3,4)#

5:

Multiplying the whole function by

#4# increases all y-values by a factor of#4# , so the new y-value will be#4# times the original value (#4# ), or#16# .Therefore, the new point is

#(-12, 16)#

6:

Multiplying the whole function by

#-1# also multiplies every y-value by#-1# , so the new y-value will be#-1# times the original value (#4# ), or#-4# .Therefore, the new point is

#(-12, -4)#
