Webf −1[f [A]] is a set, and x is an element. They cannot be equal. The correct way of proving this is: let x ∈ A, then f (x) ∈ {f (x) ∣ x ∈ A} = f [A] by the definition of image. Now ... Since you want to show that C ⊆ f −1[f [C]], yes, you should start with an arbitrary x ∈ C and try to show that x ∈ f −1[f [C]]. WebJan 4, 2016 · About this tutor ›. Use the method of u-substitution: Let u = x 2 . Then du = 2xdx. So, xdx = ½du. When x = 0, u = 0 2 = 0 and when x = 9, u = 9 2 = 81. So, ∫xf (x 2 )dx from 0 to 9 = ½∫f (u)du from 0 to 81. = ½ (14) = 7. Upvote • 1 Downvote.

That is, the derivative of a constant function is the zero function. It is easy to see this geometrically. Referring to Figure 1, we see that the graph of the constant function f(x) = c is a horizontal line. Since a horizontal line has slope 0, and the line is its ... how big do ornate bichirs get
