What are the coordinates of the vertex of the parabola with the equation y = x + 2x - 3?

The coordinates of the vertex are (-1,-4).

Step-by-step explanation:

Equation of the Quadratic Function

The vertex form of the quadratic function has the following equation:

Where (h, k) is the vertex of the parabola that results when plotting the function, and a is a coefficient different from zero.

We are given the function:

We must transform the equation above by completing squares:

The first two terms can be completed to be the square of a binomial. Recall the identity:

Thus if we add and subtract 1:

Operating:

The trinomial in parentheses is a perfect square:

Adding 4:

Comparing with the vertex form of the quadratic function, we have the vertex (-1,-4).

The coordinates of the vertex are (-1,-4).

number one is the correct answer

step-by-step explanation: dogs and cats are mentioned, no other animals

the answer is a

step-by-step explanation:

because if you put 1 in to the square root of x it equals 300.
