Question 933120
The functions are {{{y=abs(x)}}} and {{{y=abs(x-15)}}} .
Neither function has a {{{-15}}} for any kind of intercept,
and they have different y-intercepts,
so none of those 4 options is true.
The graph of {{{y=abs(x)}}} is {{{graph(300,300,-10,10,-2,18,abs(x))}}} and the graph of {{{y=abs(x-15)}}} is {{{graph(300,300,-2,18,-2,18,abs(x-15))}}} .
The graph of {{{y=abs(x-15)}}} has the same shape  as the graph of {{{y=abs(x)}}} ,
but the graph of {{{y=abs(x-15)}}} is shifted to the right by 15 units.
The graph of {{{y=abs(x)}}} has the origin , {{{system(x=0,y=0)}}} , its
y-intercept, and its x-intercept.
The graph of {{{y=abs(x-15)}}} has as its x-intercept, at {{{system(x=15,y=0)}}} ,
where {{{x-15=0}}} and so is its absolute value,
and a y-intercept is the point where {{{system(x=0,y=15)}}} ,
or the value , {{{15}}} , of the y-coordinate at that point.
