Describe the end behavior of f(x)=-2x^3 using the leading coefficient and degree, and state the domain and range
astra-53 [7]

Answer:

See explanation for end behavior below

Domain = All Real numbers

Range = All Real numbers

Step-by-step explanation:

This is a typical power function of order 3, and since its coefficient is a negative one (-2), its end behavior is:

As x becomes more and more negative (moving towards the left of the horizontal axis, the values for y will become larger and larger (reaching very positive numbers on the y scale). As x becomes larger and larger (moving towards large values on the positive side of the horizontal axis, the related y values will become more and more negative.

The Domain of the function (the x-values for which the function is defined) consists of all Real numbers.

The same is true for the Range, since the y-values spread over all the real number line.

Circle B has a radius of 7.2in. Find the diameter of circle B dilated by a factor of 8.1
Helen [10]
Since the scale factor is greater than 1, this dilation will be an enlargement. Therefore, you multiply 7.2 times 8.1 to get 58.32. This question asks for diameter, so multiply 58.32 times 2 to get 116.64 in.
