Question

Постройте график функции: y=-3^2-6x+2.ветви будут вниз.Пожалуйста срочно!!!​

Answer 1

Ответ:

у=3²-6х+2

у= 9- 6х+2

х |. 1 |. 0 |

---------------------

у |. 6 |. 11 |.

Объяснение:

Потом строишь график функций. И потом считаешь сначала координаты переменной х потом переменной у . 1 - 1 клетка. Если вниз то от низу считай

Answer 2

Plotting the Function y = -3x^2 - 6x + 2

To plot the function y = -3x^2 - 6x + 2, we can use the standard form of a quadratic function, y = ax^2 + bx + c, where a determines the direction of the parabola's opening and b affects the position of the axis of symmetry. In this case, the coefficient of x^2 is negative, indicating that the parabola opens downwards.

The vertex of the parabola can be found using the formula x = -b / (2a). Once we have the vertex, we can determine the direction of the parabola and plot the graph accordingly.

Let's proceed with the calculations to find the vertex and plot the graph.

Calculating the Vertex

The x-coordinate of the vertex can be found using the formula x = -b / (2a), where a = -3 and b = -6.

Substitute the values of a and b into the formula: x = -(-6) / (2 * (-3)) x = 6 / -6 x = -1

To find the corresponding y-coordinate, substitute x = -1 into the original function: y = -3(-1)^2 - 6(-1) + 2 y = -3 + 6 + 2 y = 5

So, the vertex of the parabola is at (-1, 5).

Plotting the Graph

Now that we have the vertex, we can plot the graph of the function y = -3x^2 - 6x + 2. The parabola will open downwards, and the vertex will be at the point (-1, 5).

Let's plot the graph of the function.
