Question

W(x)=x^3 - 5x^2 + 8x - 4
I need the x and y intercepts and the behavior of this equation.

Answer 1

x intercept is where the line crosses the x axis or where y=0
y intercept is where the line crosses the y axis or where x=0

the equation is 3rd degree and the leading coefient is positive so it goes from bottom left to top right, with 2 changes in direction (up to down or down to up)

x intercepts
W(x)=0=x^3-5x^2+8x-4
um, I graphed it and the x intercepts are at x=1 and x=2

y intercept is where x=0
W(0)=0^3-5(0)+8(0)-4=-4
the y intercept is y=-4
