Juanita plans to purchase a 50 fl. oz. shampoo at $15.10. She has a $2.15 coupon off from the store. What is the final price for the shampoo?

Answer:

The function is even because f(x) = f(−x).

Step-by-step explanation:

we know that

An even function is one for which  

f(−x)=f(x) for all x in its domain.

An odd function is one for which  

f(−x)=−f(x) for all x in its domain

In this problem we have

so

therefore

f(x)=f(-x) for all x in its domain.

Is a even function

Answer:

Option A) The function is even because f(x) = f(−x).

Step-by-step explanation:

We are given the following in the question:

We have to check whether the given function is odd or even.

Even function:

Odd function:

To check, we evaluate f(-x)

Thus, the given function is even.

The solution of the given multiplication expression is 13.5424 and the sign is positive.

What is multiplication?

Multiplication is the process of determining the product of two or more numbers in mathematics. A product, or an expression that specifies factors to be multiplied, is what happens when you multiply two numbers in mathematics.

The given multiplication expression will be solved as,

E =(-1.15) x 3.2 x (-1.15) x 3.2

E = -1.15 x 3.2 x (-1.15) x 3.2

E = -1.15 x 3.2 x -1.15 x 3.2

E = -3.68 x -1.15 x 3.2

E=  4.232 x 3.2

E=  13.5424

Therefore, the solution of the given multiplication expression is 13.5424 and the sign is positive.

Answer:

13.5424

Step-by-step explanation:

  (-1.15)*3.2*(-1.15)*3.2

  -1.15*3.2*(-1.15)*3.2

 -1.15*3.2*-1.15*3.2

-3.68*-1.15*3.2

  4.232*3.2

  13.5424
