Пошаговое объяснение:

угловой коэффициент касательной, проведенной к параболе: y=x²-3x + 2 в точке x=3 , находим так: сначала ищем производную.

по формулам :

(xⁿ)'=n*xⁿ⁻¹

x'=1

(const)'=0

(u+v)'=u'+v'

затем подставляем значение х=3

и находим значение производной.

у'(x)=(x²-3x+2)'=2x-3+0=2x-3

у'(3)=2*3-3=6-3=3
