That doesn't mean intermediate bond funds are going to go up exactly the amount that the Fed funds rate goes up (which would be 2.25% over 3 years from the current 0.75% rate to meet that projection). Even less that the Fed will do three rate hikes of 0.5% in 2017 - 0.25% are the much more likely moves, and no one, including the Fed, knows how many of them will occur this year because the Fed evaluates the current economic conditions at each meeting. In addition, no one knows how the yield curve will behave as it all unfolds.Fed rate moves don't directly control ANYTHING except overnight lending to FED member banks, but does IMPACT a lot of things.

For bond funds, the impact "rule of thumb" is duration x rate increase = decline in fund value. I would not want to take much of this "interest rate" risk (duration = 5 for the fund in question given:
"Yellen has tentatively sketched out a path of three rate hikes per year until the Fed get interest rates to 3% in 2019." - MarketWatch
If you look at the past performance of various bond funds over periods where interest rates rise, you'll get a much better idea of the impact of rising rates on total return during those years. In the real world it's not a simple formula.
