Create an equation for a cubic function, in standard form, that has x-intercepts given by the set {-3, 1, 7} and which passes through the point (-2, 54) .

Step-by-step explanation:

let the  function  be  f(x)=a(x+3)(x-1)(x-7)

∵ it passes through (-2,54)

54=a(-2+3)(-2-1)(-2-7)

54=a(1)(-3)(-9)

27a=54

a=2

so cubic is

f(x)=2(x+3)(x-1)(x-7)

=2(x+3)(x²-7x-x+7)

=2(x+3)(x²-8x+7)

=2(x³-8x²+7x+3x²-24x+21)

=2(x³-5x²-21x+21)

=2x³-10x²-42x+42

based on context clues you gave i'm assuming the answer would be c.

7. d. 64

8. i. 32

9. c. 125

10. j. none of the above

11. d. 81

12. i. 216

13. e. none of the above

14. g. 240

15. e. none of the above

16. g. 32

17.   e. none of the above
