<h2>Hello!</h2>

The answer is: f(x) = 2x^{2}

<h2>Why?</h2>

Quadratic function describes the graph of a parabola and they are formed by a quadratic term (x^{2}) a linear term (bx) and a constant number (c). Quadratic terms have an exponent of 2 and linear terms have an exponent of 1.

For this situation, we have only the quadratic term (x^{2}) which is enough to know that there is a quadratic function.

Have a nice day!

<h2>Answer:</h2>

<u>The correct choice is </u><u>f(x)= 2x²</u>

<h2>Step-by-step explanation:</h2>

In algebra, a quadratic function is a polynomial of degree 2 in which the highest-degree term is of the second degree. In other words it is a polynomial function with one or more variables which gives two answers in the end. The graph of a quadratic function is shown as a curve called a parabola. These parabolas may open upward or downward and vary in slopes but they all have the same basic "U" shape.

If the following system of equations was written as a matrix equation in the form AX = C,? and matrix A was expressed in the for
Tomtit [17]

The value of the expression a - b + c + d will be 7.

<h3>What is the matrix?</h3>

A matrix is a specific arrangement of items, particularly numbers. A matrix is a row-and-column mathematical structure. The a_{ij} element in a matrix, such as M, refers to the i-th row and j-th column element.

The system of equations are given below.

5x + 7y = 7

3x - 2y = 9​

Then the equations can be written in the form of matrix. Then we have

\begin{bmatrix}5 & 7 \\3 & -2 \\\end{bmatrix} \begin{bmatrix}x \\y \\\end{bmatrix} = \begin{bmatrix}7 \\9 \\\end{bmatrix}

Then the value of a, b, c, and d will be

a = 5, b = 3, c = 7, and d = -2

Then  the value of the expression will be

a - b + c + d = 5 - 3 + 7 - 2

a - b + c + d = 12 - 5

a - b + c + d = 7

More about the matrix link is given below.
