503/2=251.5
31/2=15.5
251.5-15.5=HARMONY
251.5+15.5=MAGLEV
HARMONY=236
MAGLEV=267

According to info given, the two added up should equal 503 and the maglev is faster than the harmony by 31, so subtracting 236 from 267 should equal 31

267-236=31
267+236=503

The other person posted an incorrect answer as the sum is not 503 in his.

Answer: $(0,0), (3,-27)$

Step-by-step explanation:

Given

Curve is $y=x^4-4x^3$

The stationary point on a differentiable function is the points where the differentiation of the function is zero i.e. slope is zero at that point.

Differentiate the curve $f(x)=x^4-4x^3$

$\Rightarrow f'(x)=4x^3-12x^2$

Equate it to zero

$\Rightarrow 4x^3-12x^2=0\\\Rightarrow 4x^2(x-3)=0\\\Rightarrow x=0,0,3$

Put $x=0,3$ in the function $f(x)=x^4-4x^3$

$\Rightarrow f(0)=0\\\Rightarrow f(3)=3^4-4(3)^3\\\Rightarrow f(3)=81-108\\\Rightarrow f(3)=-27$

Therefore, the stationary points are $(0,0), (3,-27)$
