Question

Choose the equation of the graph shown below.

y = |x - 1| - 3
y = |x + 1| - 3
y = |x - 1| + 3

Answer 1

the 1, 3 shows the coordinates of the minimum
this way, it is
y = |x + 1| - 3
as you have to invert the sign of h, which is -1, so +1

Answer 2

y = |x - 1| + 3 <--- y coordinate of vertex
^ x coordinate of vertex
for this, the vertex is (1, 3)

use similar rule and find the equation of graph.
