平行线 y= 1/2 x-3/2 (4.2)

解答

平行线

y = \frac{1}{2} x - \frac{3}{2} (4.2)

y = 0.5 x + b

求解步骤

计算

y = \frac{1}{2} x - \frac{3}{2} 4.2

的斜率:

m = 0.5

斜率 m=

0.5

的直线:

y = 0.5 x + b

y = 0.5 x + b

f (x) = x^{3} + 3 x^{2}

e x t re m e f (x) = x^{3} + 6 x^{2} + 2

cr i t i c a l \frac{x ^{2} - 7}{x - 3}

p a r a ll e l Y (x) = - 1 x + 7, (5, - 8)

e x t re m e f (x) = 9 x^{2} - x^{3} - 3
