Question

How do I write an equation with y = |x| ?
Problem: 4 units up, 2 units right

Answer 1

y = |x|


y = |x| + 4 ..... 4 units up


y = |x-2| + 4 ..... 2 units right

Answer 2

What if I have to find the vertex of (-3,0) ?

Answer 3

the vertex of

y = a|x-h|+k


is (h,k)


So (h,k) = (-3,0), which means h = -3 and k = 0


So the absolute value equation is y = a|x+3|


If a = 1, then equation is y = |x+3|

Answer 4

So is the equation y = a|x-h|+k is to find the vertex?

Answer 5

that's the general form of an absolute value equation
