- 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...
- 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)....
- 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,...
- 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...
- 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...
- A parabola is created by a quadratic function such as y=x^2. It looks like a U.
- 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...
- To 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...
- Yes he said the wrong thing but it should have been g(x)!

- Quartiles are the points (a set of three points) that divide the data into four equal parts or quarters. The first, second, and third quartile is r...
- The interquartile range (IQR) is the difference between the upper quartile $(Q_3)$ and the lower quartile $(Q_1)$. $IQR = Q_3 \;−\; Q_1$
- Mean is the average of all the numbers in the given data. It is the best way to analyze the central tendency of the data. It uses all the data poin...
Sep 11, 2020 · Range is the difference between the highest and lowest values in a data set. Learn how to calculate the range by hand or with a calculator, and how to interpret it with examples and outliers.
Learn how to calculate the range, variance and standard deviation of a data set and what they mean. The range is the difference between the largest and smallest data points, while the variance and standard deviation measure how spread out the data is from the mean.
