The vertex is (1, 4) and the sign of a is -2 How do I find the range?
are u talking about a parabola?
no the lines are linear
so what exactly is the vertex you're referring to?
Sorry I know that I sound stupid right now. lol The vertex is a graph I had to draw. The graph was y = -2 Ix - 1I + 4
no you don't sound that way... math is so broad that vertex could mean a lot of things... i'm just trying to clarify the question... and good thing i did because i thought the question was referring to a parabola... :)
so the graph is an absolute value function... y = -2|x-1| + 4
because of the -2, the vertex will be HIGHEST point in the graph....
HINT: the highest value for y is 4...
So the range would be all real numbers between -2 and 4?
no... the range is: all real numbers less than or equal to 4
I get it! :D Thankyou!
