1 pt For the function y x35x262 ts yintercept is ts rinterc

(1 pt) For the function y = x3-5x2-62, ts y-intercept is ts r-intercepts are 1 when x oo, y When x -oo, y , X2 = and X3 with T1 2

Solution

given y =x^3 -5x^2 -6x

to find out y intercept :

plug x=0

then y = 0^3 -50^2 -6*0

y =0 is the y intecept

to find out x intercept

plug y=0

then we get x^3 -5x^2 -6x=0

x(x^2 -5x -6)=0

so x=0 or x^2 -5x-6=0

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

x(x-6)+1(x-6)=0

(x+1)(x-6)=0

so x=-1 or x=-6

x1=0 , x2= -1, x3=-6

when x tends to +infinite then y = + infinite

whe x tend to -infinite then y = -infinite
