1What is the parent function of the graph?
https://tcan4424-oakcliff-ccl.gradpoint.com/Resour...

 
a.y = |x – 4|
b.y = |x|
c.y = |x| + 4
d.y = |x| – 4
 2Write the equation that is the translation of y=lxl right 7 units and down 9 units.
 
a.y=lx+9l+7
b.y=lx+7l-9
c.y=lx-7l-9
d.y=lx-9l+7

 3Which pair of equations represents perpendicular lines?
 
a.y=2x+7
y=x+7
b.y=2x+7
y=-2x-2
c.y=2x+7
y=2x-7
d.y=2x-7
y=-1/2-7
 4Identify the function in which y varies directly with x.
 
a.y=6x-2
b.y=5x+1
c.y=0x
d.y=0.3x

Since the graph has a "V" shape, the parent graph is the absolute value function y = |x|.
