Linear Functions
Linear Functions y=1/2x+1 Domain:All real numbers Range: All real numbers dependent on the input X-Intercept: The X-intercept is where the line crosses the x axis. ... Symmetry: To find the reflection of a linear function, you must take the negative reciprical of the slope, for example, the equation y=1/2x would change to y=-2x. ... Monotonic: Linear Functions are monotonic because as x increases, the output(y) stays going in one direction. Other Characteristics of Linear Functions: Linear Functions are the most basic function.
