Can you show all of the steps you take to find the answer please? Thank you

12. Find the derivative of the function. IN y = dy dx 13. Find the derivative of the function. - 10 y= 3 x dy dx 14. Find the slope of the tangent line to the graph of the given function at the given value of x. y = 9x1 /2 + x3/2; x =25 The slope of the tangent line to the graph is Simplify your answer.) 15. Find all the values of x where the tangent line is horizontal. f (x) =x5 - 3x2 - 7x+14 x = Use a comma to separate answers as needed. Type an exact answer, using radicals as needed.) 16. Differentiate. F(x) = (5x + 4)2 F'(x) = 17. Use the product rule to find the derivative of the following. y = (x+9) (31x+4) y' = 18. Find the derivative of the function. 5x - 1 y = 8x + 9 The derivative is y' = 1/7
