f(x)=(-3x^3-x^2-9x-8)/(6x^2+4x+3. Find the equation of the non-vertical asymptote. y=
Does f(x) intersect its non-vertical asymptote ?
What is the smallest value of x at which f(c) intersects its non-vertical asymptote ?
please show all the work. I did this and got the wrong answer. I want to know where I made a mistake. Thank you
By long division I got
(-3x^3-x^2-9x-8)/(6x^2+4x+3) = (-1/2)x+1/6 + ( (-49/6)x - 17/2 )/(6x^2 + 4x + 3
As x becomes ± large, the last term ----> 0
and the asymptote is
y = (-1/2)x + 1/6
The denominator can never be zero, solving 6x^2 + 4x + 3 = 0 produces complex roots.
Thus the function is continuous, and can never cross its asymptote.
The value of c we find solving the equation
