If f(x)=4^x/4^x 2 then f(1/1997)
If f(x)=4^x/4^x 2 then f(1/1997)-Then the power of the x, the 3, reduces by one becoming a 2 Therefore, the result is 12x^2 You would then do the same thing for the remaining parts of the equation x^2 becomes 2x x^2 is the same as 1x^2 so we do the number in front multiplied by the power (1 2=2) and then reduce the power by one (21=1) Consider given function f(x) = 6x – 4 Now f(8) = 6(8) 4 = 48 4 = 44 Thus, the value of function f(x) = 6x – 4 when x= 8 is 44 johnsonlogr johnsonlogr Alphonso was earning S1,860 per month and then got a 12% raise How much will he make per month now?

This example uses the basic function \(y = f(x)\) This can then be uses to draw related functions Notice that the main points on this graph are \(x = 2,\,1,\,4\) Graph of y = f(x) kIf f(x) is a product of several factors, any constants (terms in the product that do not depend on x) can be omitted For example, let f(x) = 6x 4 − 2x 3 5, and suppose we wish to simplify this function, using O notation, to describe its growth rate as x approaches infinity This function is the sum of three terms 6x 4, −2x 3, and 5F(x) f(1x) = 4 x /(4 x 2) 4 1x /(4 1x 2) = 4 x /(4 x 2) 2/(4 x 2) = 1 So f(1/97)f(96/97) = f(1/97) f(11/97) = 1 Similarly f(2/97)f(95/97) = 1 So the required sum = times Henct the required sum = 48

Composite Functions – Explanation & Examples In mathematics, a function is a rule which relates a given set of inputs to a set of possible outputs The important point to note about a function is that each input is related to exactly one output The process of naming functions is known as function notation TheNote We prove a more general exercise as following Suppose that f is continuous on an open interval I containing xIf f X!Y is continuous and V ˆY is closed, then f 1(V) is closed Another good wording Under a continuous function, the inverse image of a closed set is closed
