Kyle created this graph of a function using his graphing calculator. what is the equation of kyle’s graph? a. y=x2 b. y=3x c. y=x3 d. y=3x

The correct answer is  D. y = 3x

This is because slope is rise/run so from the origin (0,0) we can go up 3 and over 1 to get to the next point, so our slope is 3/1 or 3

Hope that helps u out!! :)

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
