Assignment 4 April‚ 7 2013 Mat222 In this week of class we have been taught how to evaluate‚ combine and find inverses of working relations or functions. We will be computing‚ composing‚ transforming and finding the inverse of some functions. We are working with the following functions: f(x) = 2x+5 g(x) = x2 -3 h(x) = (7-3x)/3 We have been asked to compute (f – h)(4). (f – h)(4) = f(4) – h(4) So we can evaluate each separately and then subtract. f(4)

MATH RATIONALE “The mathematic mind is a mind that is especially interested in mathematics. Rather than find them boring and absurd‚ they find them interesting and absorbing. It is a fact that most children in our Montessori schools manage to achieve great enthusiasm while working with mathematics. Is the preparation of their minds that allows them to reach this pleasure." Maria Montessori‚ London Lectures‚ 1946‚ p 41 Mathematics has always been a difficult subject for students. Many children

communication occurs. However‚ there may be many misperceptions that mathematics is a language. One may argue that one can utilize numbers to represent certain letters in the alphabet‚ for example‚ a= 1‚ b = 2‚ c = 3. It is just using numbers‚ to represent a language. However‚ this is not mathematics. Numbers themselves can be a language‚ however numbers are just symbols. Numbers are not mathematics. Do we use mathematics to communicate? No. This is because mathematics is not a language‚ it is a process
