x2+8= y This equation represents a function. It will be a parabola with the vertex at (0,8). You can easily graph this on a graphing calculator or from prior knowledge. You know the basic graph of y=x2 with vertex (0,0) and opens upwards on the y-axis. From the equation, you simply shift the vertex vertically up 8 so the new vertex is (0,8) This represents a function because for every x value there is one y value.
A function tries to define these relationsips. It tries to give the relationship a mathematical form. An equation is a mathematical way of looking at the relationship between concepts or items. These concepts or items ar represented by what are called variables.
f(x) = mx + bRestate the question: What are the functions that can represent a straight line?The equation y=mx + b represents all straight lines except for a vertical line, which has undefined slope.In function form, this is f(x) = mx + b. m represents the slope, and b the y-intercept.x = a represents a vertical line, which is not a function.The 'general form' of the straight line equation is Ax +By + C = 0. As long as B is not zero, this is a function.
As a straight line equation: y = -3x+18 in slope intercept form
An equation just has an equal sign. A function is basically just an equation without one!
Start with y = |x|, then y = 4|x|, and then y = -4|x|.
y = 3*f(x + 2)
x2+8= y This equation represents a function. It will be a parabola with the vertex at (0,8). You can easily graph this on a graphing calculator or from prior knowledge.

From the equation, you simply shift the vertex vertically up 8 so the new vertex is (0,8) This represents a function because for every x value there is one y value.
The [ 2x + 1 ] represents a function of 'y' .
f(x) = |f(x)|/3
If the function is a straight line equation that passes through the graph once, then that's a function, anything on a graph is a relation!
A derivative of a function represents that equation's slope at any given point on its graph.
A derivative of a function represents that equation's slope at any given point on its graph.
The letter f represents function notation, and replaces y as a variable. f(x)=ax+b is a linear function.
It is f(x) = 3|x|.
