Answer:
All of them are polynomial functions
Step-by-step explanation:
Remember that a polynomial function of x is a function whose value f(x) is always equal to 
for a fixed n≥0 (the degree of f) and fixed coefficients 
For example, 
is a polynomial function, but 
is not because 
is not a nonnegative power of x. Another example of a non-polynomial function is 
.
f(x)=4⋅11x is polynomial with degree 1 and 
. For the same reasons, f(x)=3⋅18x and f(x)=10⋅17x are polynomial functions.
f(x)=−4x³−4x²+5x+1 is a polynomial function of degree 3 with 
. and f(x)=−2x−1 is a polynomial function of degree 1 and coefficients 
.
