Answer 5

I refer to google, enter polynomial curve sketching in the search window. There are many characteristics to list and explain.

Answer 6

Some are sign of coefficient of the first term. The degree of the polynomial and the "zeroes" are just a few (without explanation how they affect the graph)

Answer 7

so why are key features necessary?

Answer 8

It is not that they are necessary, it is the fact that polynomials possess these characteristics by their very definition.

Answer 9

ohh. ok

Answer 10

key features are like whether the parabola opens up or down and stuff like that?

Answer 11

?

Answer 12

Yes, and the sign of the coefficient of the x^2 term would determine that. The "zeroes" would define where the curve touches the x axis. Polynomials are continous by definition. Again use google for a detailed rundown of the "key" features and their impact on graphing. Better yet refer to your text.

Answer 13

I should say the sign of coefficient of the leading term determines the direction of the polynomial graph.

Answer 14

thank you !
