1 answer:

3 0

y = x - 3

1. Subtract 7 from the right to the left.
* 4y = 4x - 12
2. Divide the 4 (constant) next to the 'y' to the other side.
* y = 4/4x - 12/4
* y = x - 3

The graph of this system of equations is used to solve 4x2-3+6=2x4-9x3+2x What represents the solution set?

ANSWER

x coordinates of the intersection points

EXPLANATION

The given system of equations is:

$y = 4 {x}^{2} - 3x + 6$

$y = 2 {x}^{4} - 9 {x}^{3} + 2x$

We want to use the graph of these functions to solve

$4 {x}^{2} - 3x + 6 = 2 {x}^{4} - 9 {x}^{3} + 2x$

The point of the intersection of the graph gives the solution to the simultaneous equation above.

Hence the x-coordinates of the intersection points gives the solution set of

$4 {x}^{2} - 3x + 6 = 2 {x}^{4} - 9 {x}^{3} + 2x$

The last choice is correct.

Answer:

$\boxed{\text{A. }\math{\left \{ x \, | \, x \in \mathbb{R}, x < -2 \right \}}}}$

Step-by-step explanation:

The open circle means that the point is not included in the solution set, and the arrow pointing left means that all numbers less than -2 are members.

In set-builder notation, each term has a special meaning. The braces enclose the members of the set.

Here's how you translate the notation,

$\begin{array}{rcl}\\\left \{ & = & \text{The set of}\\x & = & \text{all x values}\\| & = &\text{such that}\\x & = & x\\\in & = &\text{is a member of}\\\mathbb{R}, & = &\text{all real numbers, and}\\x < -2 & = & \text{x is less than -2}\\\end{array}\\\text{The answer is }\boxed{\textbf{A. }\mathbf{\left \{ x \, | \, x \in \mathbb{R}, x < -2 \right \} }}}$
