Let f be an increasing function with f(0) = 2. The derivative of f is given by f'(x) = sin(x) + x² + 3. (a) Find f" (-2).

Find the value of x for which line a is parallel to line b

Multiply and simplify. (x - 4) (x^2 – 5x – 6) i will mark brainliest if your answer is right. show how you got the answer. if your answer is correct but does not show how you got the answer you will not be marked brainliest.

3/4 = c/36 i need with this fraction proble.
