Given the function f(x) = 2x ? 9 a. pay off the position of change between the two stated values for x: 6 to 9 b. Find the equation of a s confines containing the given points: (6, f(6)) and (9, f(9))f(6)=2(6)-9 f(6)=12-9 f(6)=3Â  (6,3) f(7)=2(7)-9 f(7)=14-9 f(7)=5Â  (7,5) f(8)=2(8)-9 f(8)=16-9 f(8)=7 (8,7) f(9)=2(9)-9 f(9)=18-9 f(9)=9 (9,9) find the secant line (6,f(6)) and (9,f(9)) m = change in y / change in x m =((9-6/9-6)) m=((9-6/3)) m=((9-2)) m=7 m=(y2-y1/x2-x1) (y-((6))=7*(x-(6)) (y-6))=7*(x-(6)) y-(6)=7*(x-(6)) y-(6)=7(x-6) y-(6)=7x-42 y=6+7x-42 (y-((9))=7*(x-(9)) (y-(9))=7*(x-(9)0 y-(9)=7*(x-(9)) y-(9)=(7x-63) y=9+7x-63 y=7x-54 the two likely equations be y=7x-36 and y=7x-54 2. Given the following piecewise function: F(x)={-x-1 for x<-2 {3 for -2<x<3 4x for x>3 area is [-2,3] range is [-2,inf] To assoil the piecewise equation for each part. Y=mx+b Y=-x-1 for x can be slight than or equal to -2 (0,-1),(-1,0),(1,-1) Y=3 for -2, x greater, x less than 3 (1,1),(0,0) Y=4x for x is less than or equal to 3. The slope is up 4 and over 1, because either number you times 4 by is greater than 3, with comply to zero or anything negative.If you want to arise a wax essay, order it on our website: OrderCustomPaper.com
