Write a recursive definition for the sequence 21,16,11,6

If you apply the changes below to the absolute value parent function, f(x)=\x\, which of these is the equation of the new function? shift 2 units to the left shift 3 units down a. g(x)=\x-3\-2 b. g(x)= \x-2\-3 c. g(x)= \x+3\-2 d. g(x)= \x+2\-3

Can any one me with the answers to these questions asap?

If x = -2, then x 2-7x+10 equals a. 0 b.20 c.28
