Hey please answer the 3 questions attached, thank you very much!

a) negative correlation b) Diagram C (I think) c) Diagram b

Step-by-step explanation:

a) Negative= line going dow

Positive= line going up

no correlation= no line

b) the dots are to close to each other which mean it has a string correlation.

c)Its no correlation, so line should not be drawn

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
