Question

What is the degree of 7x^3 + 6^2 - 2

Answer 1

which degree you are talking abt

Answer 2

Degree is the highest/largest exponent.

Answer 3

There should be an X after the 6, so its 6x^2

Answer 4

some of my examples in my book don't have the largest as the degree

Answer 5

A second-degree polynomial, such as \(4x^2\), \(x^2 – 9\), or \(ax^2 + bx + c\), is also called a "quadratic".

A third-degree polynomial, such as \(–6x^3\) or \(x^3 – 27\), is also called a "cubic".

A fourth-degree polynomial, such as \(x^4\) or \(2x^4 – 3x^2 + 9\), is sometimes called a "quartic".

A fifth-degree polynomial, such as \(2x^5\) or \(x^5 – 4x^3 – x + 7\), is sometimes called a "quintic".

Now, knowing this, what would you say your example is?

Answer 6

3

Answer 7

It is a third-degree polynomial or a cubic-polynomial. Good job.

Answer 8

Thank You, I have a lot more problems, so I may need you lol

Answer 9

Okay, no problemo :)

Answer 10

Ok, now I have h(3)


H(x) = 2x^4 - x^3 + 2x^2 - 4x -3

Answer 11

Simple enough, just plug in 3 for all instances of x.

Answer 12

OMG DUH,I feel so dumb now

Answer 13

Nah, you're not dumb. It just takes practice. In my case, years of it :P

Answer 14

well, I have been out of school for 5 years, and I just started back to college last year.
