WebThe examples of exponential functions are: f (x) = 2 x f (x) = 1/ 2 x = 2 -x f (x) = 2 x+3 f (x) = 0.5 x Solved Problems Question 1: Simplify the exponential function 2 x – 2 x+1 Solution: Given exponential function: 2 x – 2 x+1 By using the property: a x a y = a x+y Hence, 2 x+1 can be written as 2 x. 2 Thus the given function is written as: WebIn the mathematical field of real analysis, a simple function is a real (or complex)-valued function over a subset of the real line, similar to a step function.Simple functions are sufficiently "nice" that using them makes mathematical reasoning, theory, and proof easier. For example, simple functions attain only a finite number of values.
WebA function relates an input to an output. Saying " f (4) = 16 " is like saying 4 is somehow related to 16. Or 4 → 16.
