Remove parentheses. Which would be a - 3
In Polynomials all the exponents of x-variable must be positive integers, then polynomials are:
<span>a) -x^5+7x-1/2x^2+9, the exponents of x's are: 5, 1, and 2
b) x^3-4x-3, the exponents of x's are: 3, and 1
f) x^4+x^3√7+2x^2-√3/2x+π, the exponents of x's are: 4, 3, 2, and 1
Not polynomials are:
</span><span>c) 4 / x^2-4x+3 = 4x^(-2)-4x+3, the exponents of x's are -2, and 1
d) x^4+5/x^3-√x+8=x^4+5x^(-3)-x^(1/2)+8, the exponents of x's are 4, -3, and 1/2
e) </span>|x|^2+4√x-2=<span>|x|^2+4x^(1/2)-2, the exponents of x's are 2 and 1/2</span>
The parabola opens downward
4+48=52
if you divide 52 by 4 you should get 13.
this means michael paid 13 dollars per pizza :)
