Question

the graph of a quadratic polynomial 7x^2-3x-4 is a parabola. determine the opening of the parabola. justify your answer​

Answer 1

The parabola opens upward.

Step-by-step explanation:

The graph of a quadratic polynomial 7x² - 3x - 4 is a parabola.

If leading coefficient of a quadratic polynomial is positive then the parabola opens upward.

If leading coefficient of a quadratic polynomial is negative then the parabola opens downward.

Let f(x) = 7x² - 3x - 4

Here, leading coefficient of the f(x) is 7 which is positive.

Hence, the parabola opens upward.
