Explain why the function of f(x)=4x^2+8x is neither even or odd
myrzilka [38]

Answer:

By putting x = -x in f(x) i.e. f(-x) we didn't get f(x) or -f(x) so, the function is neither even nor odd.

Step-by-step explanation:

We need to explain why the function of f(x)=4x^2+8x is neither even or odd

First we will understand, when the function is even and odd

Even function:

<em>A function is even if f(-x) = f(x) </em>

Odd function:

<em>A function is odd if f(-x) = -f(x) </em>

So, if we get the above result by putting x = -x, then we can say that the function is even or odd.

If we don't get any of the above results then the function is neither even nor odd.

So, for the given function: f(x)=4x^2+8x

Put x = -x

f(x)=4x^2+8x\\Put x=-x\\f(-x)=4(-x)^2+8(-x)\\f(-x)=4x^2-8x

So, by putting x=-x in f(x) i.e. f(-x) we didn't get f(x) or -f(x) so, the function is neither even nor odd.

What are the measures of ∠a, ∠b, and ∠c?
Fudgin [204]

Answer:

a should be 45

b should be 90

c should also be 45

Step-by-step explanation:

I know this because 180-135=45 for a

since c is also 45, beside c should be 135.

which means those angles are congruent.

since a triangle equals 180 degrees all together 180-45-45=90

so b is 90

correct me if im wrong

If 200 vitamines cost $8.75, what should 500 vitamins cost?
WARRIOR [948]
Hello!  So, the problem is saying that 200 vitamins cost $8.75, and that is what we know.  We also know that we're going to be looking at the cost of 500 vitamins, but we don't know.  The numbers presented can be put into a proportion, and that can help solve the problem.  200 to 8.75, and 500 to a number we don't know.  I'm no sure if you familiar with the how to set up a proportion, but it's saying this number over this other number (which is a fraction) equals another fraction.  Make sure that your numbers always match up, so your not saying vitamins over money equal money over vitamins.  Use cross products, divide, and then you'll have your answer.  For this problem, since yours solving for money, make sure to have two decimal points and a dollar sign.  I hoped this helped, if you have any questions shoot me a question or message.  Good luck!
