Hey guys, I'm not really sure how I should approach this.. but I'm guessing this is very easy.
Problem: Find the points on the curve y = 2x^3-3x^2-12x+20 where the tangent is parallel to the x-axis.
Please help asap...
If two lines are parallel then thier slopes are equal.
the slope of the x-axis is 0.
So, take the derivative of the equation of the curve and set it equal to 0.
and solve this equation for x.
