## Sophia.13 2 years ago Graph y= -2|x-1|+4 What is the vertex of the graph? What are the domain and range of the function? what are the x and y intercepts? How can you use the vertex and the sign of "a" to determine the range and absolute value of the function?

Make a table of x and y values. Try graphing from x=-10 to x=10, or x=-5 to x=5. If you show your table I'll help you with the other questions.

see the graph......y intercept is 2, x-intercepts are -1 and 3 i guess

|dw:1356720416444:dw| thats one graph |dw:1356720572565:dw| That another

That looks right.

vertex (1,4)

for the domain state all values that the function is defined for. For range state all possible output values.

8. stgreen

to have a basic concept about domain/range http://www.freemathhelp.com/domain-range.html
