Determine where the function f(x)= x + [|x^2|] - [|x|] is continuous. I think the correct answer is that the function is continuous for its domain but not defined at x=0. Can someone explain this problem to me and help me understand the greatest integer and absolute value functions? keywords: continuity

(See attached file for full problem description) 1) An open-top box is to be constructed from a 4 foot by 6 foot rectangular cardboard by cutting out equal squares at each corner and the folding up the flaps. Let x denote the length of each side of the square to be cut out. a) Find the function V that represents the volume

1. Apply the slope-predictor formula to find the slope of the line tangent to y = f(x) = (2x+4)2 - (2x-4)2. Then write the equation of the line tangent to the graph of f at the point (3, f(3)). My attempt... I found y first by: f(x) = (2x+4)2 - (2x-4)2 f(x) = (4x2+16x+16) - (4x2-16x+16) f(x) = (4x2+16x+16) + (-4x2+
