$\approx 128,156,000$ households Reasonable amount
We are given the function: $N(x)=-0.023(x-33.12)^2+131$, $0\leq t\leq 14$ In order to predict the number of households in 2022, we compute $N(22)$: $N(22)=-0.023(22-33.12)^2+131\approx 128.156$ The prediction seems reasonable as the number of households is increasing on average.
