Question

Match each polynomial with its end behavior. Some end behavior options may not have a matching polynomial.Column A1.f(x) = 2x3 + 3x4 + x2 - 1:f(x) = 2x3 + 3x4 + x2 - 12.f(x) = 1 - 3x + x2:f(x) = 1 - 3x + x23.f(x) = 9 + x4:f(x) = 9 + x44.f(x) = 2x + 5:f(x) = 2x + 5Column Ba.As x gets larger and larger in the positive direction, f(x) gets larger and larger in the positive direction. As x gets larger and larger in the negative direction, f(x) gets larger and larger in teh negative direction.b.As x gets larger and larger in either the positive or negative direction, f(x) gets larger and larger in the positive direction.

Answer 1

The correct answer is:

1. b

2. b

3. b

4. a

The first three functions have a positive coefficient and the biggest power is an even number. This means that no matter if the values are positive or negative, the image will always be positive.

In the last function, which is a linear equation, is clear the b option.
