1. is the function f(x)=5x^2-3x^4+3/4x-7 a polynomial function? if so, state its degree and the leading coefficient. a. the function is not a polynomial b. the function is a polynomial. the degree is 2 and the leading coefficient is 5 c. the function is a polynomial. the degree is 4 and he leading coefficient is -3. d. the function is a polynomial. the degree is 4 and the leading coefficient is 5.

A polynomial is an equation where we have different coefficients and variables, such that the order of the polynomial depends on the exponents of these variables that must all be whole numbers.

We will see that the correct option is C:

"The function is a polynomial. The degree is 4 and the leading coefficient is -3. "

Here the function is:

The variable is x, and we can see that all the exponents are whole numbers, so yes, this is a polynomial.

Now we also want to find the degree and the leading coefficient of this polynomial.

The degree is the largest exponent of the polynomial, which we can see is 4.

And the leading coefficient is the coefficient of the term with the largest exponent.

In this case, the leading coefficient is -3.

Then the correct option is:

C: "The function is a polynomial. The degree is 4 and the leading coefficient is -3. "

Step-by-step explanation:

If we put this polynomial (yes it is a polynomial) in order of descending powers of x, it would be

The definition of a polynomial is an expression of more than 2 algebraic terms, especially the sum of several terms that contain different powers of the same variable(s).

Not just a sum.  A difference too, but since every subtraction problem can be written as an addition, that's why they say "the sum of several terms".  The degree of the polynomial is the same as the highest power of x.  Ours is a 4th degree.  The leading coefficient is the first number that leads the polynomial when it is put into order of descending powers of x.  Our coefficient is -3.  To sum up:

Yes, it is a polynomial; it is a degree 4 with a leading coefficient of -3

That is choice C

step-by-step explanation:

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
