The rectier function ()i 0 ifcc N55) and 3(55) 5 r(:t:) for all 2:, and p(93) and r(:n) are both continuous. 2. (a) (b) Explain why p(:c) approximates r(23) well for large (positive and negative) values of :9. Explain why 5(a) approximates r(2:) well for large (positive and negative) values of 2:. 3. Where is p(m) the worst approximation to r(:c)? In other words, where is the vertical distance between the two functions maximized? 4. (a) On the interval (700, 0), where is 5(33) the worst approximation to rm)? You may not be able to determine an exact xvalue, but nd the integer a
