Please type the problem in, since it will be not harder than typing the image was, and make sure everything is correct. You have missing parentheses, varying case (B vs b), and other issues that make it hard to be sure what things mean.

If possible, also show us an image of the actual, original problem to be sure. In particular, I want to be sure what "tangent crossing point" and "image with known function" mean to you.

Then show us whatever work you have done, even if that is only speculations about what it means. That's what we need in order to help you where you are.
