Question

Find conditions on a,b and c so that the graph of y=ax^3+bx^2+cx has one tangent line
parallel to the x axis.

Answer 1

find the derivative of the function, equate the result to zero, then solve the quadratic equation

Answer 2

please explain it detail or can you make it... seriusly i can't do

Answer 3

@sirm3d please

Answer 4

show the way, please

Answer 5

the tangent line requires that you compute the derivative of ax^3 + bx^2 + cx. can you compute its derivative?

Answer 6

no..:(

Answer 7

what is the derivative of x^3?

Answer 8

this is a calculus problem so computing the derivative is a must-know

Answer 9

oh ya.. i don;t know calculus, this is my brother assignment. i just eager how to do it... calculus seems fun n interesting.. i want to learn

Answer 10

lol...

Answer 11

a=0?
