Find the domain of the function. (Enter your answer using interval notation.)

Question

f(x)= 9-1/2x if X < 2

9x-2 if x>2

Answer 1

9-1/(2x) has domain (-inf,0) U (0,2]

or maybe you meant 9-(1/2)x, if so, then domain is x< 2 or (-infinity, 2]

"9 -1/2x" means 9-1/(2x) but some people seem to write it to mean 9-(1/2)x especially on Wyzant problems, even though it's not what it means.

9x-2 [2, infinity)
