Cell Phone Ad Spending Cell phone advertising spending is expected to grow at the rate of \[ R(t)=0.8256 t^{-0.04},(1 \leq t \leq 5) \] billion dollars/year between \( 2007(t=1) \) and \( 2011(t=5) \). The cell-phone ad spending in 2007 was \( \$ 0.9 \) billion. \( t \) (a) Find an expression \( f(t) \) giving the cell phone ad spending in year \( t \). \[ f(t)=0.8256(2015-2006)^{-0.04} \] (b) If the trend continued, what was the cell-phone ad spending in 2012? (Round your answer to two decimal places.) \[ \$ 7.40 \] billion
