This paper presents a reciprocal way for realizing asymmetric optical transfer functions (OTFs) in the reflection side of the on-axis processing channels. To reflect about the y-axis, multiply every x by -1 to get -x. Since the variable x is in the denominator of a fraction the domain of the function will be restricted to where the denominator cannot be equal to zero. Analog computing has emerged as a promising candidate for real-time and parallel continuous data processing. Follow the following steps to find the equation of a reciprocal function from the graph: Step 1: Find the vertical asymptote. Strech. How to sketch exponential graphs and reciprocal graphs? A polynomial function and its related reciprocal function have the same positive and negative intervals. For example, this figure shows the parent function f(x) = x 2 and the reflection … Reflection.
