Determine the end behavior of the polynomial function. f(x)=-3x^4-2x^3+2x^2+ 3x +5 a) falls to the left and rises to the right b

Molodets [167]

Answer:

Option b is correct

Step-by-step explanation:

In order to check the end behavior of a polynomial function we just check the leading term and its coefficient and the procedure is as follows:

Here we can see that highest exponent of the polynomial function is 4

therefore degree of the polynomial is 4. and therefore $-3x^4$ is leading term.

because of even degree it will be same from both ends that is either both sides rises or both sides falls. Since number in the front of leading is negative therefore it falls at both ends. that is falls to the left and falls to the right.

therefore option b is correct.

Which equation results from applying the secant and tangent segment theorem to this figure? x(x 2) = (x 4) x(x 4) = (x 2) x(x 4)

fomenos

The equation which is results from applying the secant and tangent segment theorem to the provided figure is,

$x(2x +4) = (x +2)^2$

<h3>What is secant and tangent segment theorem?</h3>

The secant-tangent theorem tells the relation of the line segment made by a tangent and the secant lines with the connected circle.

According to this theorem, if the tangent and secant segments are drawn from an exterior point, then the square of this tangent segment is equal to the product of the secant segment and the line segment from that exterior point.

The image of the given problem is attached below. In the attached image, the tangent is given as,

$T=x+2$

The secant is shown in the image has the value,

$S=x+x+4\\S=2x+4$

Now according to the secant tangent theorem,

$x(2x +4) = (x +2)^2$

Hence, the equation which is results from applying the secant and tangent segment theorem to the provided figure is,

$x(2x +4) = (x +2)^2$
