- If g(x)=x^2/x and x^2/x=x then can we say that: g(x)=x And if we can, how than for x=0 this expressi...When you start with a reciprocal function, you will have at least one vertical asymptote in which the function does not have a value. So by startin...
- OK so I'm totally lost by this. Is this at all like the domain on the function? They seem totally di...The domain of a function is the set of all acceptable input values (X-values). The range of a function is the set of all output values (Y-values)....
- what is the difference between f(x) and y values?f(x) is Y. The equation `f(x) = 2x - 5` is the same a `y = 2x - 5` provided the equation with Y is a function. Not all equation are functions. So,...
- At 2:22 Sal says that the definition is F(x) is going to be equal to x^2. Does that mean that if I h...Yes - that is how it works, if you have f(x)=x² and are asked what is f(2), then you replace every instance of x in the function definition with 2...
- Sorry if this was asked already but what is a non real number and what would an example be?Non-real numbers are called imaginary numbers and are based on i=√-1. You cannot take the square root of negative numbers, so you move to imaginary...
- what is parabolaA parabola is created by a quadratic function such as y=x^2. It looks like a U.
- What if the input is an imaginary number (i) ? how will the graph be?You do not graph imaginary numbers on the Cartesian plane, you move to the Argand plane (or plot or diagram) which is also called the complex plane...
- At 3:43 why cant y be negative? Is this true for all problems or only dis oneTo answer you question of if it is always true, the answer is no. If you start from the quadratic parent function, y=x^2, then y cannot be negative...

The formula to calculate the range is: 1. R= range 2. H= highest value 3. L= lowest value The range is the easiest measure of variability to calculate. To find the range, follow these steps: 1. Order all values in your data set from low to high. 2. Subtract the lowest value from the highest value. This process is the same regardless of whether your...
The range generally gives you a good indicator of variability when you have a distribution without extreme values. When paired with measures of central tendency, the range can tell you about the span of the distribution. But the range can be misleading when you have outliersin your data set. One extreme value in the data will give you a completely ...
