a)what does the number 3.03 represent
What does "g" represent? If you plug in "1" for "g", what does the answer mean?
jonesbetty wrote:b) find C(2)
Plug "2" in for "g". Simplify.

Plug "9" in for "g". Simplify.

If you're not familiar with cars or driving, try asking an adult (like your mom) about gas tanks, etc.

Where are you having difficulty on this part?
