The graph of absolute parent function is vertically stretched by a scale factor of two then shifted three units left eight units down which equation could represent this function (A) f(x)=2|x+3|-8
(B) f(x)=2|x-3|-8
(C) f(x)=1/2|x+3|-8
(D) f(x)=1/2|x-3|-8

The function a represents the cost of manufacturing product a, in hundreds of dollars, and the function b represents the cost of manufacturing product b, in hundreds of dollars. a(t) = 5t + 2 b(t) = 7t - 2t +4 find the expression that describes the total cost of manufacturing both products, a(t) + b(t). a. 7t^2 - 7t + 2 b. 7t^2 + 3 +6 c. 7t^2 + 7t - 6 d. 7t^2 - 3t + 6

Ineed to know the answer to this algebra question.

Last one and the bottom answer choice is y=(x-4)^2+1 you guys!
