Functions with same form, diff parameters
fโฒ(x)=(xโa)(3xโaโ2b)f'(x) = (x - a)(3x - a - 2b)fโฒ(x)=(xโa)(3xโaโ2b)
Where fโฒ(x)=0f'(x) = 0fโฒ(x)=0
x=a+2b3x = \frac{a + 2b}{3}x=3a+2bโ
Always a local maximum
fโฒ(x)>0f'(x) > 0fโฒ(x)>0 (positive)
(a,b)(a, b)(a,b) and (2+a,โ4+b)(2 + a, -4 + b)(2+a,โ4+b)
(0,0)(0, 0)(0,0) and (2,โ4)(2, -4)(2,โ4)
Two: point on curve and fโฒ(x)=0f'(x) = 0fโฒ(x)=0
a=cโ12a = c - 12a=cโ12
