Yes, it would.

Explanation:

The structure of 4-methylcyclohexene is

Structure

The compound has two alkene #"=C-H"# bonds, and they have a stretching vibration in the region between #"3100 cm"^"-1"# and #"3000 cm"^"-1"#.

Thus, we should expect to see a sharp peak to the left of #"3000 cm"^"-1"#.

The infrared absorption spectrum of 4-methylcyclohexene has a sharp absorption peak at #"3063 cm"^"-1"#
