Which of the following are polynomial functions? Check all that apply.A. F(x) = 3x-^3 - 19
B. F(x) = 2x^2 + 5x - 3
C. F(x) = -x^3 + 5x2 + 7x - 1
D. F(x) = -x^3 + sq -x
E. F(x) = 3/5x^4 - 18x^3 + x^2 - 10x + 3.5

Answers

Answer 1
Answer:

The function F(x) = 2x² + 5x – 3, F(x) = -x³ + 5x² + 7x – 1, and F(x) = 3/5x⁴ – 18x³ + x² – 10x + 3.5 are polynomial function. Then the correct options are B, C, and E.

What is polynomial?

A polynomial expression is an algebraic expression with variables and coefficients. Unknown variables are what they're termed. We can use addition, subtraction, and other mathematical operations. However, a variable is not divisible.

The polynomial is given below.

\rm f(x) = a_0x^n + a_1 x^(n - 1)+ ....+ a_(n-2)x^2 + a_(n-1)x + a_nx^0

If the exponent of the variable is negative and fraction, then the function is not a polynomial function.

A. F(x) = 3x⁻³ – 19, the exponent of the function is negative 3. Then the function is not a polynomial function.

B. F(x) = 2x² + 5x – 3, the exponent of the function is whole number. Then the function is a polynomial function.

C. F(x) = -x³ + 5x² + 7x – 1, the exponent of the function is whole number. Then the function is a polynomial function.

D. F(x) = -x³ + √(-x), the exponent of the function is 1/2. Then the function is not a polynomial function.

E. F(x) = 3/5x⁴ – 18x³ + x² – 10x + 3.5, the exponent of the function is whole number. Then the function is a polynomial function.

Then the correct options are B, C, and E.

There are 2 loaf of bread in each row how many loaves of bread are there in 5 rows

Answers

There are 2 loaves of bread in each row. To find out how many loaves of bread are in five rows, we have to multiply the number of loeaves of bread in each row (2) by the number of rows (5). 2 x 5 = 10 Thus, there are 10 loaves of bread in 5 rows. Hope this helps! :)
There are 10 loafs of bread in five rows, because 5 times 2 equals 10
