Just take the lowest number in the series, in the case of A) -29.7, and then take the largest number (25.5). The domain is from -29.7 to 25.5. Then just use whatever notation you want. Ex. -29.7<=x<=25.5

Okay. So would my answer be choice A?

anonymous · Answer

No, in this case it would be B. x = domain, y = range. Sorry if my previous answer confused you.

its okay, no worries..thanks for the help : )
