What is the equation of the absolute value function?

Question

geerky42 · Answer

First, we need to find vertex of this function. Do you know what it is?

anonymous · Answer

Not at all

anonymous · Answer

Thanks for coming @campbell_st

campbell_st · Answer

the vertex is the corner of the graph. Which is the point (-3, 4)

the standard form is 

y = | x - h| + k

where the vertex is at (h, k)

substitute the actual vertex information into the standard equation

hope it helps

does that make sense? @Shay17

anonymous · Answer

Ok I will post the answer choices

campbell_st · Answer

I know the answer... what happens if you substitute h = -3 and k = 4

anonymous · Answer

$$A. y \le \left| x-5 \right|-5$$

anonymous · Answer

$$B. y \ge \left| x-5 \right|+5$$

anonymous · Answer

$$C. y \le \left| x+5 \right|+5$$

geerky42 · Answer

let's not forgot a in y = a|x - h| + k

anonymous · Answer

$$D. y \le \left| x-5 \right|+5$$

Are you sure you post correct graph? because none of these options are correct.

geerky42 · Answer

or other way around? lol

anonymous · Answer

Ok let me check

anonymous · Answer

Sorry about that

geerky42 · Answer

ah so that's correct one. like campbell_st said, vertex is corner of the graph.

do you know the point of that corner?

anonymous · Answer

Uhhhh. no
