How to A. sketch the graph of the function by applying the leading coefficient test, B.finding the zeros of the polynomial c. plotting sufficient solution points and d. drawing a continuous curve through the points.
f(x)= 3x^3 - 24x^2
Thank you for the opportunity to help you with your question!
A. since the leading coefficient 3>0, the function looks like 3x^3 as x goes to -infinity and infinity.
B. 3x^3-24x^2 = 3x^2(x-8)
zero is x = 0 or x = 8,
since x =0 has x^2, the function >0 near x =0,
d. x <8 f(x)<0, and f(x)>0 for x>0,
Thanks! Can you show me the steps for finding the zeroes?
just let 3x^3-24x^2 = 3x^2(x-8)=0, so we have
then we have
