Anuta_ua [19.1K]

Answer:

Firstly, to create a sequence we need our natural numbers which will stand for our n and the pattern created will be f(n). where n = 1, 2, 3, 4, . . .

1. If we have f(n) = n + 1, then our sequence would be 2, 4, 5, 6, . . . with a pattern of adding 1 to our n.

2. If we have f(n) = n x 2, then our sequence would be 1, 4, 6, 8, . . . with a pattern of multiplying 2 by our n.

3. If we have f(n) = n + 2 when n is odd and n - 1 when even, then we have 3, 1, 5, 3, . . . as our sequence following the add subtraction pattern.

4. if we have f(n) = n x 2 when n is odd and n/1 when n is even, then we have 2, 4, 10, 6, . . .

Which system of equations can be graphed to find the solution(s) to x2 = 2x + 3?

Effectus [21]

ANSWER

The correct answer is
$y = {x}^{2}$
and
$y = 2x + 3$

EXPLANATION

The given equation is

${x}^{2} = 2x + 3$

If we consider this equation as a single equation, then we can use methods such as factorization, completing the squares, or the quadratic formula to solve it.

For instance using the method of factorization we proceed as follows,

${x}^{2} - 2x - 3 = 0$
${x}^{2} - 3x + x - 3 = 0$

$x(x - 3) + 1(x - 3) = 0$

$(x - 3)(x + 1) = 0$

$x = - 1 \: or \: x = 3$

Meaning when we graph the function
$y = {x}^{2} - 2x - 3$
, it will intersect the x-axis at
$x = - 1 \: and \: x = 3$

However, if we consider the equation to be two different systems combined, that is the equation of the straight line

$y = 2x + 3$
and the equation of the basic quadratic function
$y = {x}^{2}$

Then the solution to
${x}^{2} = 2x + 3$
is the intersection of the graph of the straight line and the graph of the quadratic curve.

That is the x-coordinates of the points of intersection are the solutions.

See graph.
