Three cylinders have a height of 8 cm. cylinder 1 has a radius of 1 cm. cylinder 2 has a radius of 2 cm. cylinder 3 has a radius of 3 cm. find the volume of each cylinder ( ! : ”0 )

Solve the inequaliy: (x^2+2)(x−2)^2(6−2x)> 0

Which statement best describes how to determine whether f(x) = x squared- x +8 is an even function ?
