Use the graph to find the indicated function values a f1 b

Use the graph to find the indicated function values. (a) f(-1) = (b) f(0) = (c) f(1) = (d) f(2) =

Solution

Domain means x-values covered by graph so that will be
Domain: (-2,2]

there is hole on left side that\'s why i used ( not [

Range means y-values covered by graph so that will be
Range : [-5,4]

f(-1) simply means find y-value when x=-1
f(-1)=-5
f(0)=-4
f(1)=-5
f(2)=4
