Question

F(x) =2x^2 -5x+17;k-3

Answer 1

Ответ:2

Пошаговое объяснение:

Находим производную

f '(x)=-4x+5

Находим ее значение в точке х=3/4

f '(3/4)=-4*3/4+5=2

Тангенс угла наклона касательной равен значению производной. Поэтому

tgα= f '(3/4)=2

Ответ: 2

Answer 2

It seems like you're providing a mathematical expression $F(x) = 2x^2 - 5x + 17$ and mentioning $k - 3$, but it's not entirely clear what you'd like to do with this information. Are you looking to evaluate $F(x)$ at a specific value of $x$, solve for $x$ when $F(x) = k - 3$, or something else? Please provide more context or clarify your question so I can assist you accurately.
