we are stuck in doing this absolute-value functions. We are trying to understand the x and y intercept in this problem:
y=[x-1.8] +2.9
vertex (1.8, 2.9)
axis of symmetry: x=1.8 because 1.8 added to -1.8 makes x in the absolute value 0
x-intercept: 1.8
y-intercept we are not sure. would it be -1.8 or 4.7
