differentiation

[plucky bridge]

Can someone help me with ii

The answer is (3,45) but idk how to get there

[royal shard]

what ever the gradient of the tangent is at P

put that equal to the dy/dx

eg if the gradient at p was 2 then dy/dx = 2

then manipulate it and find for x

and plug in the x to the original equation to get y coordinate

[strange kayak]

essentially u get the gradient you got for P and equate it to ur derivative. then solve the new quadratic and you will get ur value for x to be 3 and plug this into the equation of the curve

Oh damn
