Answer:

y = -8x² - 3x - 10

Step-by-step explanation:

Given points

  • (-5,-195)
  • (-3,-73)
  • (1,- 21)

We know ,

  • y = ax² + bx + c .

From 1st point ,

  • -195 = x(-5)² + b(-5) + c
  • -195 = 25x - 5b + c . . . . . (i)

From second point ,

  • -73 = -9a -3b + c . . . . . (ii)

From 3rd point ,

  • -21 = a + b + c . . . . . (iii)

Solving (i) , (ii) and (iii) , we have

  • a = -8
  • b = -3
  • c = -10

On substituting ,

  • y = -8x² - 3x - 10
