need answerDiesel$-$powered light vehicle sales in the United States are shown in table for various years. Let $s=f(t)$ be the U$.$S$.$ annual diesel$-$powered

light vehicle sales $($in millions of vehicles$)$ at $t$ years since $2010.$ Complete parts $($a$)$ through $($d$)$ below.

a$.$ Find an equation of $f.$

A$.s=-0\mathrm{.}011t^2-0\mathrm{.}086t-0\mathrm{.}279$

B$.s=0\mathrm{.}09\sqrt[\phantom{2}]{t}+0\mathrm{.}28$

C$.s=-0\mathrm{.}011t^2+0\mathrm{.}086t+0\mathrm{.}279$

D$.s=0\mathrm{.}09\sqrt[\phantom{2}]{t}+0\mathrm{.}2$

b$.$ What is the s$-$intercept? What does it mean in this situation?

The s$-$intercept is $(0,0\mathrm{.}28).($Type an ordered pair.$)$

What does the s$-$intercept mean in this situation? Select the correct choice below and fill in the answer box to complete your choice.

$($Round to two decimal places as needed.$)$

A$.$ In $2010,$ the U$.$S$.$ annual diesel$-$powered light vehicle sales was at a minimum.

B$.$ In $2000,$ the U$.$S$.$ annual diesel$-$powered light vehicle sales was million vehicles.

C$.$ In $2010,$ the U$.$S$.$ annual diesel$-$powered light vehicle sales was $0\mathrm{.}28$ million vehicles.

D: In $2010,$ the U$.$S$.$ annual diesel$-$powered light vehicle sales was at a maximum.

c$.$ Find $f(11).$ What does it mean in this situation?

$f(11)=0\mathrm{.}58$ million vehicles

$($Round to two decimal places as needed.$)$
