Question 1114029: please I need help with these two questions
Describe the graph of each equation (shape, location by quadrants, etc.) – each equation a function or not? Why or why not?
Use the vertical line test
State the domain and range for each relation in interval notation
Perform the transformation of one of the graphs as indicated in the prompt and write the new equation .
first question is f(x)=-2x+4
second question is y=|x|-4

------------------------------- .
first question is f(x)=-2x+4
shape:: a line
location:: left to right: II,I,IV
intercept:: (0,4)
slope:: -2
function?: yes
domain:: All Real Numbers
range:: All Real Numbers
-----------------------------------
second question is y=|x|-4
shape:: V-shaped; opening up from (0,-4)
location: symetric to y-axis
intercepts:: (0,-4); (-4,0) and (4,0)
function?: yes
domain :: All Real
range:: [-4,+oo)
