well you can make an equation from the fact that the curve has a s.p at 4.3
Okay thanks
You know the plus C when integrating f’(x) is -5 as that’s where it cuts y axis
You know there’s a stationary point at where x = 4 so plug that in and set f’(x) equal to 0 and there’s equation 1
Once you integrate as normal, use this fact
Then plug in x = 4 and y = 3 and that’s equation 2
And then solve them simultaneously for a and b
And there’s your equation for f(x)
