Hello, can someone help me solve this question: y = √(x^2 - 6x + 13) find the coordinates of the point on the curve where the gradient is 0.
I assume gradient means slope and not the normal.
1) Find dy/dx
2) You should get a fraction with x in both numerator and denominator.
3) In order for a fraction to be 0, then the numerator must be 0
4) Set the numerator equal to 0 and solve for x
5) Substitute that value of x back into the original to get the corresponding y value
You should get (3,2)
okay, thank you and yes it does mean the slope
let us know if you have trouble with step 1
