"A trough is to be made by bending a long rectangular piece of tin 3

feet wide. The cross-section of the trough is an isosceles trapezoid

with sides making angles of 120 degrees with the base. Find the

dimension of the cross-section which gives a maximum capacity"

The questions states that the base is 1ft, the top is 2ft and the height is √3/2ft

Thank you!

]]>Thank you for your question. The function f(x) = |2x+3| is neither odd nor even because it is not symmetrical with respect to the y-axis and it has no point symmetry. f(-x)=|2(-x) +3| = |-2x+3|. You can't just turn the negative to a positive in this case because there is also +3 there. Enter this function into Desmos to see what it looks like.
