Which of the following is a polynomial function? select all correct answers. select all that apply: f(x)=4⋅11x f(x)=3⋅18x f(x)=10⋅17x f(x)=−4x3−4x2+5x+1 f(x)=−2x−1

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 .

d

step-by-step explanation:

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
