Question

A function is defined by the rule:
g(x) = 3 for x less than or equal too 0
g(x) =3cos(x) for x>0

state the DOMAIN and RANGE for g(x)

Answer 1

the domain is given, since it includes x-values less than or greater than zero
domain is all real numbers

range must include 3
cos(x) ranges from -1 to 1 so 3cos(x) ranges from -3 to 3
Range is -3 to 3

Answer 2

ngawwww i see THANK YOU @dumbcow
