One of the two sets of functions, fi, f2, fa, or g1, 92, ga, is graphed in Figure 13.1; the other set is graphed in Figure 13.2. Points A and B each have a = 0. Taylor polynomials of degree 2 approximationg these functions near a = 0 are as follows: hi(x) = 2+ 1+ 2- 91(3) =1+r+ 2- f(x) = 2+1-1' "(r)=l+r+x fa(x) = 2+1+1 (3)=1-rtr. (a) Which group of functions, the fs or the gs, is repre- sented by each figure? (b) What are the coordinates of the points A and BY (c) Match each function with the graphs (1) (III) in the appropriate figure. III II B Figure 13.1 Figure 13.2
