Is this set of ordered pairs a function?
{(0, 2), (3, 3), (8, 7), (2, 2), (3,9) }

no it is not a function

Step-by-step explanation:

no

Step-by-step explanation:

(0,2) and (2,2) have the same y value.

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

days of the week

step-by-step explanation:

javier earned more money then kyle, so that won't always be a constant term, but the days of the week do not change so that term is always constant.
