LHS: =

We know
so we can replace the sin²x in the LHS expression as follows
which is the RHS.
Domain is the set of names
Range is set of times
C. $34.50. A car gets 30 miles per gallon, if the gasoline cost $1.15 per gallon, a 900 miles trip will cost $34.50
This exercise can be solved by simply arithmetic.
Divide the total miles by the miles per gallon:
900/30 = 30
Then, multiply this value by the cost per gallon:
30 x $1.15 = $34.50
We can determine the limit by direct substitution. f(-1) is 2, and thus that is the limit there. g(2), however, does not exist because the left and right limits do not agree
