How to write an equation for functions

Functions main problem is to find the missing variable. A function is an equation in which all of the variables are dependent. For example: if you buy 2 bags of oranges and you pay ten dollars for them but the amount of money you pay for the oranges would change each time you add another bag of oranges and how much you owe for the oranges is the dependent variable. So writing a equation would mainly look like this:

$2x = 10\\v2 = c\\$

<span>So each time you add another bag of oranges the number will increase v3, v4, etc...

Hope this helps!

A function is an equation that has only one answer for y for every x. A function assigns exactly one output to each input of a specified type. It is common to name a function either f(x) or g(x) instead of y. f(2) means that we should find the value of our function when x equals 2.

What is an exponent? Because i am confused

ollegr [7]

An exponent is a number written above and to the right side of a value or number in math. The value or number is called the base, and the expression is read out as;

"Base raised to the power of exponent."

An example is given below;

$10^3$

In this example, 10 is the base and 3 is the EXPONENT.

The expression is now read out as,

"10 raised to the power of 3"

Note that even unknown values (such x as we commonly use in math) can also be an exponent or base. For example, we can have;

$\begin{gathered} 10^x \\ OR \\ 2x^3 \end{gathered}$

So basically, an exponent indicates the number of times a number is used to multiply itself.

Answer:

Q matches to a and P matches to b

Step-by-step explanation:

This is a volume question so we can use the volume of a cylinder to see which one corresponds to what. Volume of a cylinder is $\pi$ $r^{2}$ h. We know that the heights of the cylinders are the same since the diagram says so. We also know pi is the same since thats a constant. The only thing thats different is the radius (as you can see radius of P is bigger than Q). If the radius of P is bigger than Q and all the other things are the same (height is the same and pi is the same), then that automatically means that P has more volume than Q. More volume means more time to fill up. Since Q has less volume, it will take less time to fill up. So now we look at the graph. A shows that the height of water increases at a faster rate than that of B. This is because there is less volume in that container (less volume=less time to fill up). Therefore a matches to Q and therefore b matches to P
