Find the relevant domain and range for the following function. The function \( P ( t ) = 25000 + 2200 t \) models the population of a city from years 1980-2005, with \( t = 0 \) representing \( 1980 \) . The domain is \( \square \) (Give answer in correct interval notation. Do not place any spaces.). The range is \( \square \) (Give answer in correct interval notation. Do not place any spaces.). 

122. Постройте график функции \( y=-x^{2}+2 x+8 \) и найдите, ис- пользуя график: а) значение функции при \( x=2,5 ;-0,5 ;-3 ; \) б) значения аргумента, при которых \( y=6 ; 0 ;-2 \); в) нули функции и промежутки знакопостоянства; г) промежутки возрастания и убывания функции, область зна- чений функции.

(a) Express the distance \( d \) from \( P \) to the origin as a function of \( x \). \( d(x)=\sqrt{\mathrm{x}^{4}-3 \mathrm{x}^{2}+4} \) (Simplify your answer. Type an exact answer, using radicals as needed.) (b) What is \( d \) if \( x=0 \) ? If \( x=0 \), the distance \( d \) is (Type an integer or decimal rounded to two decimal places as needed.)
