NEED HELP PLZZZ Write an equation that represents the transformations formed by the following items
(a) horizontally shifting the graph 4 units to the left of f(x) = sqrt(x) and then vertically compression by a factor of 1/3
(b) vertically stretching the graph by a factor of 4 of f(x) = sqrt(x) and then vertically shifting the graph 3 units up
(c) horizontally stretching the graph of f(x) = sqrt(x) by a factor of 2 and then vertically shifting the graph units down
