Step-by-step explanation:
A polynomial is a sum of terms, each of which is the product of a constant and some constellation of variables to integer non-negative powers. Anything with a variable in a denominator, a non-linear function such as absolute value, or square root (a fractional power) will <em>not</em> be a polynomial.
The constants in a polynomial may be rational or irrational. The polynomials we generally study are ones with real coefficients, but there is no reason why the coefficients could not be complex numbers.
The cactus one I think is 0.875
Y = 2(x - 10) + 8
y = 2(x) - 2(10) + 8
y = 2x - 20 + 8
y = 2x - 12
