Draw the graph:
f(x) = x+1 for x< -1
f(x) = x2 + 3 for x>=-1
(Remember the graph should be in the range of x) After drawing the graph you will get a solution for domain and range.
For part c,d,e:
c. f(-10), meaning x = -10 and find y.
if x = -10 you will use the first equation f(x) = x+1 because x is less than -1.
f(-10) = -10 + 1
=-9
do something for d,e.
