I can solve this for the x-values that make the equation true:<br>x^2 = 8 – x^2<br>2x^2 = 8<br>x^2 = 4<br>x = –2, +2<br>Then the solutions to the original system will occur when x = –2 and when x = +2.<br>What are the corresponding y-values? To find them, I plug the x-values back in to either original equation. I'll plug the x-values into the first equation, because it's the simpler of the two:<br>x = –2:<br>y = x^2<br>y = (–2)^2 = 4<br>x = +2:<br>y = x^2<br>y = (+2)^2 = 4<br><br>Then the solutions (as w ...

Sometimes it is called the image, or more precisely, the image of the domain of the function. Range is also occasionally used to indicate the difference between the largest and smallest numbers in a set of real-valued data. If f is a surjection then its range is equal to its ...

Zero is an example of this scenario because you cannot divide by zero. <br> <br>f(x) = 6/x In this example, the domain is represented as x = <> 0. <br> <br>Linear Equations<br>A linear equation is an algebraic equation in which each term is either a constant or the product of a constant and (the first power of) a single variable. Linear equations can have one or more variables. A typical form of a linear equation is y = mx + b. These type of equations form straight lines. The constant “m” determines the slope of ...

Preview: ... al line such as x = 3, you can't make this into a function. You can only put in the number 3, and any number can come out. [The point (5, y) is on the line for any value of y.] A function isn't allowed to do this. Therefore, a linear function is never graphed by a vertical line. The slope-intercept form can describe any linear function. <br>A function always outputs a value. Suppose the function <br>f(x) = 10x + 20, what this means is that this function outputs different values for different input values of variable 'x'. For example: f(10) = 10 10 + 20 = 120, <br>f(20) = 10 20 + 20 = 220. i.e. we substitute different values into x and get different outputs. The important point is that every function outpu ...
