Question

Find the end behavior for the model P(x)=13x^123,898? I have this question on a homework assignment and can't figure out how to solve this.

Answer 1

Is this function odd power or even powered?

Answer 2

Even. Its end behaviour for both is up in the y direction.

Answer 3

Even powers always have their ends going the same ways - a parabola, for instance - and it opens up if a positive coefficient and down if a negative coefficient.

Answer 4

So you look at the "898" to determine that it is even?

Answer 5

You look at the last digit.

Answer 6

123,898 is certainly even, as it divides by 2.

Answer 7

ah, okay that help a lot! Thank you!
