What can you say about the end behavior of the function f(x)=-4x^6+6x^2-52

shepuryov [24]

Answer:

As x gets smaller, pointing to negative infinity, the value of f decreses, pointing to negative infinity.

As x gets increases, pointing to positve infinity, the value of f decreses, pointing to negative infinity.

Step-by-step explanation:

To find the end behaviour of a function f(x), we calculate these following limits:

$\lim_{x \to +\infty} f(x)$

And

$\lim_{x \to -\infty} f(x)$

In this question:

$f(x) = -4x^{6} + 6x^{2} - 52$

At negative infinity:

$\lim_{x \to -\infty} f(x) = \lim_{x \to -\infty} -4x^{6} + 6x^{2} - 52$

When the variable points to infinity, we only consider the term with the highest exponent. So

$\lim_{x \to -\infty} -4x^{6} + 6x^{2} - 52 = \lim_{x \to -\infty} -4x^{6} = -4*(-\infty)^{6} = -(\infty) = -\infty$

So as x gets smaller, pointing to negative infinity, the value of f decreses, pointing to negative infinity.

Positive infinity:

$\lim_{x \to \infty} f(x) = \lim_{x \to \infty} -4x^{6} + 6x^{2} - 52 = \lim_{x \to \infty} -4x^{6} = -4*(\infty)^{6} = -(\infty) = -\infty$

So as x gets increases, pointing to positve infinity, the value of f decreses, pointing to negative infinity.

Which list shows the numbers in order from least to greatest?

podryga [215]

Answer:

The answer to your question is: letter b

Step-by-step explanation:

Data

√32 ≈5.65

5.2

4 2/3 = 4.67

√17 ≈ 4.1

a) This option is ot correct because √17 must be the first number not the last.

b) This is the right option, all the numbers are in the right position

c) This option is wrong because 4 2/3 must be the second number in the list not the first.

d) This option is also wrong because 5.2 must be the third number in the list not the first.

Flx) = 2x + 6, 8(x) = 4x<br>Find (f+g)(x)

andrezito [222]

Answer:

I think there must be g(x) instead of 8(x) in the question. You can look the solution but i have corrected it and then solved it.

A roll of wire holds 3 meters of wire. about how many inches of wire does the roll hold?

Luda [366]

Since 1 meter is equivalent to 39.37 inches,
then we convert:
3 meters * (39.37 inches / 1 meter)
= 118.11 inches

Tamara finds the sum of two number cubes rolled at the same time. The chart below shows all possible sums from the 36 possible c

yarga [219]

Answer:

Tamara should expect the sum of the two cubes to be equal to 5 20 times.

Step-by-step explanation:

The sample space of rolling a number cube are:

S = {1, 2, 3, 4, 5, 6}

If two such cubes are rolled together, then the sum of the two cubes will be 5 for the combinations below:

S₁ = {(1, 4), (2, 3), (3, 2) and (4, 1)}

The total number of outcomes will be, N = 36.

Compute the probability that the sum of rolling two numbered cubes as follows:

Let X = number of time the sum of the two numbers on two cubes is 5.

Two numbered cubes are rolled n = 180 times.

The event of getting a sum of 5 in independent of the other results.

The random variable X follows a Binomial distribution with parameters n = 180 and p = .

The expected value of X is:

Compute the expected number of times Tamara expects the sum of the two cubes to be equal to 5 as follow:

Thus, Tamara should expect the sum of the two cubes to be equal to 5 20 times.
