Question

Over what interval is the quadratic function decreasing?

Answer 1

The interval over which the given quadratic equation decreases is:  x ∈ (5, ∞).

How to find the interval of quadratic functions?

Usually a quadratic graph function decreases either when moving from left to right or moving downwards.

In the given graph, we can see that the coordinate of the vertex is (5, 4) after which the curve goes in the downward direction.

Thus, for the values of x greater than 5, the function decreases and so we conclude that the interval in which the quadratic equation decreases is: (5, ∞).

Answer 2

The interval in which the quadratic equation decreases is:

(5, ∞).

When is the function decreasing?

The function decreases when, reading from left to right, we can see that the function goes downwards.

In this particular graph, we can see that the vertex is at the point (5, 4). And after that, the right arm goes downwards.

Then for the values of x > 5 the function decreases.

Then the interval in which the quadratic equation decreases is:

(5, ∞).
