Answer:

B. The function has an even degree.

Step-by-step explanation:

We have been given an image of a polynomial function. We are asked to choose the correct options about our given polynomial.

A. The function has a negative leading coefficient.

Upon looking at our given graph, we can see that it is an upward opening parabola, so leading coefficient can't be negative, therefore, option A is not true.

B. The function has an even degree.

Upon at our given graph, we can see that it is symmetric to y-axis, therefore it has an even degree polynomial and option B is the correct choice..

C. The function has zero turning points.

Upon looking at our given graph, we can see that as function approaches towards 0 from negative infinity it is decreasing. As function increases positive infinity from 0, it is increasing, therefore, our function has a turning point at $x=0$ , therefore, option C is incorrect.

D. The function has one x-intercept.

Since our function never intersects x-axis, therefore, function has no x-intercept and option D is incorrect as well.

Is -2.9 a rational or integer or whole or natural number

Burka [1]

Answer:

Step-by-step explanation:

It might help to get artsy/crafty with this. I made it out of construction paper, but I'm going to tell you how to draw it.

Draw a large circle, over have the page. Every number, ever, even the numbers in the smaller circles, go into this circle, fractions, decimals, negatives, zero, whole numbers, every number. Negative infinity to positive infinity and everything in between. These are rational numbers.

Now draw a smaller circle inside that one. In the smaller circle there are positive and negative numbers, but no fractions. Every number in this circle is also in the larger circle, but not every number in the bigger circle in in this smaller one. Negative infinity to positive infinity, no fractions. These are integers.

Draw a smaller circle inside the smaller one. No negative numbers in this one, only positive numbers and zero. 0 to infinity, no fractions. These are whole numbers.

One more circle inside the smallest one. Only positive whole numbers in here. No zero. 1 to infinity, no fractions. These are natural numbers.

-2.9 is negative and decimal, so not a natural, not a whole, not an integer. That leaves rational.
