What is the gradient of the blue line?

gradient = - 5

Step-by-step explanation:

Calculate the gradient (slope) m using the slope formula

m =

with (x₁, y₁ ) = (- 2, 5) and (x₂, y₂ ) = (- 1, 0) ← 2 points on the line

m = = = - 5

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

27 +27 or 27times 2=54

the diffrence is 0
