Step-by-step explanation:
Domain means the change in x.
so the domain will be which values of x the fn goes through.
you can see the black line goes from -9 to 2 in x values.
the -9 isn't filled in, but the 2 is. filled in means it will be with an equals instead of without.
so x is between -9 and 2, 2 is with equals -9 is without,
so the first one.
Since x represents the year, year 15 will be 15 years.
Plug in "15" as your "x"
y = -2(15)^2 + 36(15) + 6
15^2 = 225 (Exponents come before multiplication)
y = -2(225) + 36(15) + 6
y = -450 + 540 + 6
y = 90 + 6
y = 96
