    Answer:

    -(1×1+2). (x+3)-2. 3. Linear Function shrunk vertically by a factor of 12. 4. … 4((x-3²-5). 4(~25) g(x)= 4(x-3) -20. 6. f(x) = 2 | 4x +3| + 7; translation 2 units down … x – y – 2z = 4 b) 4x – 4y – z = 2. – x + y + 2z= -3 many no solution solutions. 10. … 2121x+11) = 4x+1. 44-x+11 9(x) = 4 |-x+4. 41-(x-3)+. 2. f(x) = 4×2 Vertical translation …
