Definition of a function Now let's learn about functions. A function is a relation where each x is paired with no more than one y. Note that the same y can be paired with different x's, but not the reverse. All linear equations, with the exception of vertical and horizontal lines, ...
What is a short definition of like terms? What is a variable? What is interpolation and extrapolation? Find the equation of the line between these two points A (0, 8) and B (-4, 0). What do you need to know to graph the linear inequalities -3x-5y-15 Given the equation y=-4x+...
Which are linear functions? a. f(x) = 2x \\b. f(x,y) = 2x + y^2 \\c. f(x,y,z) = x + 3y + 2z \\d. f(x) = e^x What is the value of f(5) for the function f(x) = 3x - 4? Suppose that y' = k y, y(0) = 3, and y'(0) = 7. What is y as a...
Linear regression is linear in that it guides the development of a function or model that fits a straight line -- called a linear regression line -- to a graph of the data. This line also minimizes the difference between a predicted value for the dependent variable given the corresponding in...
If you're learning about graphs, you're bound to see a bunch of linear equations, so it's a good idea to understand what makes an equation a linear equation. This tutorial explains linear equations and shows you the difference between equations that are linear and ones that are not. Check...
What is a quadratic function?Question:What is a quadratic function?function:A function is a relation between two sets which maps one element to one and only one element in another set. It is represented by f(x) where x is the independent variable.Answer...
What is a Parabola? If you graph a linear function, you get a line. If you graph a quadratic function, you get something called a parabola. A parabola tends to look like a smile or a frown, depending on the function. Check out this tutorial and learn about parabolas!
Artificial intelligence definition Artificial intelligence (AI) is a vast branch of computer science concerned with a development in software that allows computer systems to perform tasks that imitate human cognitive intelligence, such as visual perception, speech recognition, decision-making, and language...
Linearity: The gradient function is linear. This means that for any scalar constants a and b and functions f and g, the gradient of the linear combination af + bg is equal to the linear combination of the gradients a∇f+b∇g. Additivity: The gradient of a sum of functions is equal...
