Graphs that represent y as a function of x

Like other functions, f (x) = a g (bx), if a is negative (outside) it reflects across x axis and if b is negative it reflects across the y axis. So for square root functions, it would look like y = a √ (bx). Outside reflect across x such as y = -√x, and inside reflect across y such as y = √-x. It works for all functions though many ...

Exponential functions with bases 2 and 1/2. The exponential function is a mathematical function denoted by () = ⁡ or (where the argument x is written as an exponent).Unless otherwise specified, the term generally refers to … This test involves drawing a vertical line through the graph. If the vertical line intersects the graph at only one point for every x-value, then the graph represents y as a function of x. On the other hand, if the vertical line intersects the graph at two or more points for any x-value, then the graph does not represent y as a function of x. Linear equations are equations that have two variables and can be plotted on a graph as a straight line. Math is Fun teaches you how to solve linear equations, how to use them in real life, and how to manipulate them algebraically. You can also learn about the slope and intercept of a line, and how to write the equation of a line from two points. One convenient use of "f (x)" is that we can use separate equations/functions and not confuse ourselves. e.g.: f (x) = 3x + 4. g (x) = (1/2)x - 2. If we used y, then we could get confused by whether or not we were talking about the same equation/function. So using function notation removes the confusion there.
