Answer 1

9) Given that fla=-X, 91V= 22-22 Curves so U zo SD SO Now above two intersect when flui= girl - X=2x-x2 x2_2x-x=0 x² 3x zo x(x-3)=0 xzol x-320 223 So when x=0, y=f1Y)=-22-020 V= 3, y=f(2)= -2=-3=-3 in teqsection points are (7,4)= 10,0) and (3,-3) lane Given sitl= bet NOW know that formula for average value of function is given by s sits at -20 asteb since we need to find average sales on fiast 4 weeks. so osta 4. so a=D) b=41 we b Isang b-a in 0 .so Now plug all the values It zet de Sang = 40

savg= 4 det at = 4 [Bet] *(384-32°3 = flereº) = 1021) 4 so Sang= 4 s le 1) One
