Quadratic means 2nd degree

means highest power of variable is 2


c(x)=6x+3x^3
3rd degree, not quadratic

d(x)=x-8x^4,
4th degree, not quadratic

p(x)=-5x-x^2
2nd degree, it's quadratic

k(x)=2x^2+9x^4
4th degree, not quadratic

answer is p(x)=-5x-x^2

A pool pass costs $30 for the first month and $15 each additional month. Construct an explicit rule in function notation to mode
noname [10]

Answer:

F(n)=15(n+1)    [ where n is number of months]

F(12)=195

Step-by-step explanation:

Pool pass cost for first month =$30

Pool pass cost after first month = $15 for each month

The total amount charged by the pool can be expressed as a  function F(n) where n represents the number of months.

F(n)=15(n-1)+30

This can be simplified by using distribution.

F(n)=(15n-15)+30

F(n)=15n-15+30

F(n)=15n+15

Take 15 as greatest common factor.

∴ F(n)=15(n+1)

For n=12

F(12)=15(12+1)

F(12)=15(13)

F(12)=195

∴ Amount charged by pool for 12 months = $195

Simplificar A=4x2-6x2+7x2-20x2+19x2
maks197457 [2]

Answer:

4x²

Step-by-step explanation:

Your equation is 4x² - 6x² + 7x² - 20x² + 19x².

Since they all have the same variable, simply combine them all to find your answer.

4x² - 6x² + 7x² - 20x² + 19x²

-2x² + 7x² - 20x² + 19x²

5x² - 20x² + 19x²

-15x² + 19x²

4x²
