Question

Use your graphing calculator to solve the equation graphically for all real solutions

x^3 -6 x^2 + 6 x + 8 = 0

Answer 1

y=x^3−6x^2+6x+8

Answer 2

I don't know how to find the real solutions (which I think is the x-intercepts)

Answer 3

Are you going to graph that

Answer 4

Yeah, I did on my TI-83 but I can't really see anything

Answer 5

go to graph
2nd "Trace" for calc
zeros

(I don't have my ti in front of my right now sorry)

that might help better

Answer 7

x intercepts are where the graph passes through the x axis

Answer 8

Factor to know
