Re: degree one

I need this one too.

Write three quadratic equations, with a,b, and c (coefficients of x^2, x and the constants as
1. Integers
2. Rational numbers
3. Irrational numbers

Also is there a page where I can download x-y graphs?

Do you know what each of the three terms mean?

Re: degree one

I just do not know how to do the equations.

Re: degree one

Okay I got the problems for integers and rational, just give an irrational equation using x^2, x, and constant, please.

Re: degree one

Okay let's try this one more time. I need 3 quadraric equation examples with a, b, and c (coeffients of x^2, x and the constants as.
1 integers
2. rational numbers
3. irrational numbers
Thank You

Re: degree one

I'm not sure what you mean. Do you mean the solution or the coefficients?

The question is just to find any quadratic where a,b and c are irrational. So you just need to chosse any three irrational numbers. Do you know what an irrational number is?

For example you can choose a=√2, b=pi. I leave for you to find a third irrational number for c.

Re: degree one

No what it means is, do one quadratic equation with integers, and one with rational numbers, and one wirh irrational numbers with a, b, and c (coeffients of x^2, x, and constants.

Re: degree one

I need help really bad here.
1. Think of a real life situation that can be represented by a logarthmic function, translate the situation to the function and solve the
    function and represent it graphically.
2. Think of a real life situation that can be represented by a exponential function; translate the situation to the function; sove the
    function and represent it graphicaqlly.

Re: degree one

1. There are many uses, one of which being they are useful for astronomy when you need to multiply big numbers.
2. One that comes to mind is the number of bacteria in a petri dish. As the numbers increase, it gets more and more full in the petri dish, making it more crowded and less bacteria can survive.
