Question

The point on the curve y = 5x – x^2at which
normal is perpendicular to the line x+y=0
1) (3, -6) 2) (3,6) 3) (-3,-6) 4)(6, 3)​

Answer 1

Answer:

5

Step-by-step explanation:

First you have to find the x coordinate of the point where the curve meets the y-axis. This occurs at x=0. Then you take the first derivative of the function using the product rule and then the chain rule. Then you substitute x=0 into the derivative function to get the gradient or slope.

you should get 5 as an answer.
