Answer: Choice D

y goes to negative infinity for both cases of x going to infinity or negative infinity.

==========================

Explanation:

The degree of this function is 4, as it is the largest exponent. The even number degree tells us that the end behavior is that either

case A: the endpoints rise together

or

case B: the endpoints fall together

In short, the endpoints are more or less mirror copies going in the same direction.

In this case, both endpoints fall together as the leading coefficient (-3) is negative. As x heads off to infinity, y will go to negative infinity. As x heads off to negative infinity, y will also go to negative infinity. Regardless of which direction x goes, y will go downhill.

note: your book may refer to this as "fall to the left and fall to the right".

Please can someone answer this.

Answer:

  •  x = -4, x = 0, x = 1

Step-by-step explanation:

x is a factor of all terms, so x=0 is a zero. (Eliminates choices 1 and 5.)

The sum of coefficients is 0, so x=1 is a zero. (Eliminates choices 3 and 4.)

Reversing the sign of the odd-degree terms gives signs of -++, so there is one sign change, hence one negative real root (by Descartes' rule of signs). This confirms choice 2 as the answer.

___

Of course, your graphing calculator can answer this almost as quickly.

Verify experimentally that the angle opposite to the longer side is greater than
Veronika [31]

Answer:

If two sides of a triangle are unequal, the angle opposite to the longer side is larger (or greater). You may prove this theorem by taking a point P on BC such that CA = CP.

Step-by-step explanation:

That's how you can prove which side is bigger
