I need to invest 5,000.00. What type investment will grow fast?

The one with the most risk will yield the greatest return. The guy who jumps from the alley, guaranteeing to double your $ in one week, is high risk: a 4% per year CD is low risk. Determine your tollerance for risk, and pick your poison between the two extremes.

I don't think there is a "fast" way. Six month Certificates of Deposit are safe, and pay better interest than savings accounts and money markets.
