Answer:
Step-by-step explanation:
x is greater or equal to 13
Answer:
Second option
Step-by-step explanation:
For a set to represent a function, each input value in the set domain should match with one and only one output value of set range.
The option that follows this rule os second option as 1 is matched with 2 only, and 3 is matched with 3 only, and 5 is matched with 7 only.
Given zeroes are:
x1 = -6
x2 = 5
x3 = -2
The general formula for cubic function that has zeroes is: (factor form)
(x-x1)*(x-x2)*(x-x3)
if we express our zeroes we get:
(x+6)*(x-5)*(x+2) = (x^2 - 5x +6x - 30)(x+2) = (x^2 + x - 30) ( x+2)=
x^3 + x^2 -30x +2x^2 + 2x - 60 = x^3 +3x^2 -32x - 60
