Connecting to water line stubs left at construction

I'm looking to install a utility sink on my patio that already has water lines that are capped off by the builders. If I am correct there is also a capped off drain pipe available. Are the water lines in the picture pex pipes? If so, do I just cut off the end caps to connect fittings? I appreciate any additional help on the best way to install my utility sink to the lines below. thx!
