Which equation is best represented by the graph above (x+1)(x-3)(x+2). please explain why

Nat2105 [25]

<h3>Answer:</h3>

y = (x +2)(x -1)(x -3) . . . . or . . . . y = x³ -2x² -5x +6

<h3>Step-by-step explanation:</h3>

The graph shows y=0 at x=-2, x=1, and x=3. These are called the "zeros" or "roots" of the function, because the value of the function is zero there.

When "a" is a zero of a polynomial function, (x -a) is a factor. This means the factors of the graphed function are (x -(-2)), (x -1) and (x -3). The function can be written as the product of these factors:

... y = (x +2)(x -1)(x -3) . . . . . the equation represented by the graph

Or, the product can be multiplied out

... y = (x +2)(x² -4x +3)

... y = x³ -2x² -5x +6 . . . . . the equation represented by the graph

HELP ON THIS PROBLEM!!<br><br> Solve the following 0deg< x< 360deg: cos x= cos 2x

blsea [12.9K]

Answer:

$x=0^\circ,120^\circ,240^\circ,360^\circ$

Step-by-step explanation:

<u>Use identities to set the equation up as a quadratic</u>

$\cos x=\cos 2x;\:0^\circ \leq x \leq 360^\circ\\\\\cos x=2\cos^2 x-1\\\\0=2\cos^2 x-\cos x-1$

<u>Make the substitution u=cos(x) and solve the quadratic</u>

<u /> $0=2u^2-u-1\\\\0=(2u+1)(u-1)$

$\displaystyle 0=2u+1\\\\0=2\cos x+1\\\\-1=2\cos x\\\\-\frac{1}{2}=\cos x\\\\120^\circ,240^\circ=x$

$0=u-1\\\\0=\cos x-1\\\\1=\cos x\\\\0^\circ,360^\circ=x$

Hence, $x=0^\circ,120^\circ,240^\circ,360^\circ$

Which function does this graph correspond to?

tiny-mole [99]

ANSWER

The function that the given graph corresponds to is
$f(x) = (x - 2)(x - 1)(x + 1)(x + 2)$

EXPLANATION

The given graph in the attachment has x-intercepts at

$x = - 2 ,x=-1,x=1 \: \: and \: \: x=2$

These are the solutions of the polynomial function represented by the given graph.

We can write all these solutions as factors to obtain,

$x + 2 ,x + 1 ,x - 1 \: \:and \: \: x - 2$

The product of all these factors gives us the function whose graph was drawn.

This implies that,

$f(x) = (x - 2)(x - 1)(x + 1)(x + 2)$

Therefore the correct answer is option C.
