Could the equation. For the graph of the function have degree 4?explain
aivan3 [116]

The graphed polynomial seems to have a degree of 2, so the degree can be 4 and not 5.

<h3>Could the graphed function have a degree 4?</h3>

For a polynomial of degree N, we have (N - 1) changes of curvature.

This means that a quadratic function (degree 2) has only one change (like in the graph).

Then for a cubic function (degree 3) there are two, and so on.

So. a polynomial of degree 4 should have 3 changes. Naturally, if the coefficients of the powers 4 and 3 are really small, the function will behave like a quadratic for smaller values of x, but for larger values of x the terms of higher power will affect more, while here we only see that as x grows, the arms of the graph only go upwards (we don't know what happens after).

Then we can write:

y = a*x^4 + c*x^2 + d

That is a polynomial of degree 4, but if we choose x^2 = u

y = a*u^2 + c*u + d

So it is equivalent to a quadratic polynomial.

Then the graph can represent a function of degree 4 (but not 5, as we can't perform the same trick with an odd power).

According to modern science. Earth is about 4.5 billion years old and written human history extends back about 10,000 years. Sup
ser-zykov [4K]

Answer:

the clock will represent 4.5 billion years as 2.67 hours

Step-by-step explanation:

Data provided in the question:

Total time of history of Earth = 4.5 billion years

Representation of total time of history of Earth on clock = 12 hours

Therefore,

4.5 billion years = 12 hours

or

⇒ 1 billion year = \frac{\textup{12 hours}}{\textup{4.5}}

or

⇒ 1 billion year = 2.67 hours

Hence,

the clock will represent 4.5 billion years as 2.67 hours
