Question

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?

Answer 1

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.

Answer 2

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

Answer 3

thats one graph
That another

Answer 4

That looks right.

Answer 5

vertex (1,4)

Answer 6

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

Answer 7

to have a basic concept about domain/range

How can you use the vertex and the sign of "a" to determine the range and absolute value of the function?
