Write the equation of the graph. a. y + 3 = -1/2 ( x - 1 )b. y - 3 = 1/2 ( x + 1 )c. y - 3 = -1/2 ( x + 1 )d. y = 1/2x + 5

1.what effect does replacing x with x−4 have on the graph for the function f(x) ? f(x)=|x−6|+2 the graph is shifted 4 units up. the graph is shifted 4 units down. the graph is shifted 4 units left. the graph is shifted 4 units right. 2.what are the coordinates of the hole in the graph of the function f(x) ? f(x)=x^2+3x−28/x+7 3.which graph represents the function?
