H=H(t) represents the number of households that own ...blah...
t years 1996. So
H(0) is the number of households in the year 1996; we're told that
H(0)=62 (since
H is the number of households in millions).

At the end of each year, this number increases by 4.85%, i.e. a factor of 1.0485. This means after 1 year, the number of households is


H(1)=1.0485H(0)\approx65

After 2 years, or 1 year after the first year elapses, the number is


H(2)=1.0485H(1)=1.0485^2H(0)\approx68

After 3 years,


H(3)=1.0485H(2)=1.0485^3H(0)\approx71

and so on, with the general pattern of


H(t)=1.0485^tH(0)\implies\boxed{H(t)=62\cdot1.0485^t}

This is the function you're asked to find.
