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.

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