If y = 2x2 - 5x + 7 is graphed in the ry-plane, which of the following characteristics of the graph is displayed as a constant or coefficient in the equation? А L-intercept(s) B y-intercept I-coordinate of the vertex D y-coordinate of the vertex​

Respuesta :

Here, we are required to identify the characteristic of the graph which is displayed as a constant or coefficient in the equation y = 2x2 - 5x + 7.

The characteristic of the graph which is displayed as a constant or coefficient is the;

The characteristic of the graph which is displayed as a constant or coefficient is the;y - intercept.

According to the question; the equation

y = 2x2 - 5x + 7. is a quadratic equation.

Consequently, when graphing the equation;

Parameters required include the solutions of the graph (i.e the x - intercepts) and the y - intercept.

The x - intercept can be gotten by setting y to 0 and solving the equation quadratically.

Similarly, the y - intercept is the point which corresponds to the zero point of x.

Therefore, from the equation: y = 2x² - 5x + 7;

When we set x = 0;

y = 7 = constant.

Therefore, the characteristic of the graph which is displayed as a constant or coefficient is the;

y - intercept.
