Question 342304
Your answers are correct.
I guess just draw a number line from -15 to 25 and highlight the values at x=-14 and x=20. 
{{{number_line(600,-15,27,-14,20)}}}
.

.
You could also say
{{{y=abs(x-3)-17}}}
and that {{{y=0}}} at {{{x=-14}}} and {{{x=20}}}
.

{{{drawing(300,300,-25,25,-25,25,grid(1),circle(-14,0,1.3),circle(20,0,1.3),graph(300,300,-25,25,-25,25,abs(x-3)-17))}}}
