What is the resultant equation of a quadratic function that touches the x-axis at 1, cuts the y- axis at -1 and passes through the points (-1,-4) and (2,15)? No answer needed, take the points.

2(7+28)3= 180     (not answer)

Step-by-step explanation:

Thanks for them!!

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

35x 3= 105

step-by-step explanation:

35+35= 70   70 + 35= 105
