Using the method of u-substitution, ∫53(4x−6)4dx=∫baf(u)du where u= 4x-6 (enter a function of x) du= (2x^2-6x) dx (enter a function of x) a= 6 (enter a number) b= 14 (enter a number) f(u)= ((u)^5)/5 (enter a function of u). the value of the original integral is 132512/5 . note: you can earn full credit if the last answer box is correct and all other answer boxes are either blank or correct.

Graph a triangle (xyz) and reflect it over the line y=x to create triangle x’y’z’. describe the transformation using words. draw a line segment from point x to the reflecting line, and then draw a line segment from point x’ to the reflecting line. what do you notice about the two line segments you drew? do you think you would see the same characteristics if you drew the line segment connecting y with the reflecting line and then y’ with the reflecting line? how do you know?
