Answer:
A polynomial is something like:
y = a*x^n + b*x^(n-1) + .... + g*x^0
n is the degree of the polynomial, a is the leading coefficient and g is the constant.
d(x) = x + pi
a) For a polynomial, the standard form is the form i write above, so here we have
d(x) = x + pi = 1*x^1 + pi*x^0
b) this is a linear polynomial (as all the polynomials of degree 1)
c) the degree is 1, because the biggest power of x that we have is x^1 = x.
d) The leading coefficient is the constant that is multipliying the highest power of the polynomial, in this case we have:
d(x) = 1*x + pi
1 is the leading coefficient.
e) the constant is the coefficient that multiplies the term x^0 = 1.
here we have:
d(x) = x^1 + pi*x^0 = x + pi
So the constant term is pi.
