Решение 2. №7 (с. 103)

Тангенс угла наклона касательной к графику функции в некоторой точке равен значению производной этой функции в данной точке. Это следует из геометрического смысла производной: $k = \text{tg}\alpha = f'(x_0)$, где $\alpha$ – это угол наклона касательной, а $x_0$ – абсцисса точки касания.

1. Нахождение производной функции.

Дана функция $f(x) = 2x^3 - 5x$.

Найдем её производную, используя стандартные правила дифференцирования:

$f'(x) = (2x^3 - 5x)' = (2x^3)' - (5x)' = 2 \cdot 3x^{3-1} - 5 \cdot 1x^{1-1} = 6x^2 - 5$.

2. Вычисление значения производной в точке касания.

Касательная проведена к графику в точке $M(2; 6)$. Абсцисса этой точки равна $x_0 = 2$.

Теперь необходимо вычислить значение производной $f'(x)$ в точке $x_0 = 2$:

$f'(2) = 6 \cdot (2)^2 - 5 = 6 \cdot 4 - 5 = 24 - 5 = 19$.

Таким образом, тангенс угла наклона касательной, проведенной к графику функции $f(x) = 2x^3 - 5x$ в точке $M(2; 6)$, равен 19.

Среди предложенных вариантов ответа это соответствует варианту B.

Ответ: B) $\text{tga} = 19$.
