Which polynomial is a quadratic trinomial?
il63 [147K]
<h3>Answer: Choice C</h3>

The largest exponent here is 4, so that makes it a quartic.

There are 3 terms, so we have a trinomial. Each term is separated by either a plus or a minus.

Choice A shows a quartic polynomial. Choice B is a cubic polynomial. Choice d is a quadratic trinomial.

Which function , A or B has a greater rate of change ? Be sure to include the values for the rates of change in your answer . Ex
arsen [322]
<h2>Answer:</h2>

A rate of change tells us  how one quantity changes in relation to another quantity. In a mathematical language, we can write this as follows:

Rate \ of \ Change=\frac{Change \ in \ y}{Change \ in \ x}

For linear functions. the rate of change is the slope of the line. Thus:

FOR THE TABLE:

By taking two points we can get the rate of change, so let's take (1,5) \ and \ (2,7):

ROC=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\ \\ ROC=\frac{7-5}{2-1} \\ \\ ROC=\frac{2}{1} \\ \\ \boxed{ROC=2}

FOR THE GRAPH:

Let's take (1,1) \ and \ (2,4):

ROC=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\ \\ ROC=\frac{4-1}{2-1} \\ \\ ROC=\frac{3}{1} \\ \\ \boxed{ROC=3}

As you can see, 3>2 so <em>the ROC of the function given by the graph is greater than the ROC of the function given by the table.</em>
