andrew-mc [135]

<h3>Answer</h3>

Given in the question the equation

y = x² - 2x + 6

Name

a quadratic polynomial or a polynomial of degree 2

Ind. var

An input value of function is the independent value = x

Dep. var

The output value of function is the dependent value, as it depends on the value of the input = y

Rule

a function is a rule that assigns to each input exactly one output.

Evaluation

when x = -3

y = (-3)² - 2(-3) + 6

= 21

See below for the solution to the systems of equations

<h3>How to solve the systems of equations?</h3>

<u>System of equations 1</u>

Here, we have

3x - 4y = -16

3x + 4y = 8

We start by plotting the graph of both equations

Next, we write out the point of intersection of the equations

See attachment for the equation of the system

From the attached graph, the point of intersection of the equations is (-4/3, 3)

Hence, the solution to the system is (-4/3, 3)

<u>System of equations 2</u>

Here, we have

-x = - 6 + 2y

-18 + 6y = -3x

We start by plotting the graph of both equations

Next, we write out the point of intersection of the equations

See attachment for the equation of the system

From the attached graph, both lines are on each other

This means that the system of equations have infinite many solutions
