Question

ha Fill in the blanks to correctly complete the following sentence. The graph of f(x) = - 5x2 - 9x + 8 opens down with y-intercept (0,5), so it has x-intercept(s). no two one

Answer 1

1. 
   Ques =) f(x) - 5x2-9X+8 Solution for y-interupt pest X=0 in f(x) = f(x) = -5x2–9x + 8 f101= -5(0)2-910)+8 > flol: 0-0 +8 > flol 8 7 = y-in tercept! (0,8) s for -in tercept peet f(x) = 0 5) -5x2-9x+8 = 0 wce a=-5, b=-9 and 628 d ca 8 → 6²-40c=1-93²4x45) 88 5) 6?_yac = 81 + 16oz १41 =) by quadratic formal a x=-bt Jb²4ac ga
   
   >>> X = 9+ J241 2x.(-5) >x=19 + 1241 and x=19-5291 -10 - 10 => x-intercept : 1- 2 r sort o) and (95AT SO) ~ The graph of f(x) = - 5x²_9x+8 opens down with y-intercept 10, 8) has two x-intercepts. 9 So it
