Terms
It is a polynomial if the square root is in a coefficient but not if it is applied to the variable. A polynomial can have only integer powers of the variable. Thus: sqrt(2)*x3 + 4*x + 3 is a polynomial expression but 2*x3 + 4*sqrt(x) + 3 is not.
1 2 3 and 4 are 4 numbers, they are not functions of any sort - cubic polynomial or otherwise.
23x + 16 are terms. This would only be an equation If there was an equal sign.
The degree of a polynomial refers to the largest exponent in the function for that polynomial. A degree 3 polynomial will have 3 as the largest exponent, but may also have smaller exponents. Both x^3 and x^3-x²+x-1 are degree three polynomials since the largest exponent is 4. The polynomial x^4+x^3 would not be degree three however because even though there is an exponent of 3, there is a higher exponent also present (in this case, 4).
It is the inequality: 23x + 4 > 12.
Are those x's or multiplication signs?
If: y = -2x+4 and y = 23x-4 Then: -2x+4 = 23x-4 And: -25x = -8 So: x = 0.32 and by substituting y = 3.36 Intersection: (0.32, 3.36)
6x2+23x+20=0x= .7275 and -4.5634Improved Answer:-6x2+23x+20 = (3x+4)(2x+5) when factored
youranswer would be -23x+y=-253 because you add 23x to both sides (to y and itself)
That already is a polynomial in standard form.
4x-23x = -19

23x - 9x = 14x
15x^2+3x-12 3(5x^2+x-4)=Answer
If you mean: y = -23x+3 then the parallel equation is y = -23x+164
A quadratic polynomial.
