Answer:
a
Explanation:
step 1:
for x is less than -5 the f(x) = -3
step 2:
for x is greater than or equal to -5 and less than or equal to 15, f(x)=x+2 and since x contains the value of 15 the Value of x=15 results in f(x)=x+2 15+2=17.
step 3
for x is greater than 15, f(x)= -x+2.
only exists in the graph a.
