12. The logarithmic function y = log. (x) has been transformed to a function whose domain has remained unchanged. Which of the following functions could represent the transformed to nismob edT function? A. y = 4f(x) +3 B. y = 4f(-x) - 4 C. y = A(x+ 4)+3 D. y = 4f( x - 4)+ 3 Hint: Horizontal reflections and translations can affect the domain. equron A Jail Alsups cholshimonso 13. The function f(x) = log. (x) has been transformed to g(x) =- 4log. (x + 5). The graph of g (x) could be found by A. reflecting the graph of f(x) in the x-axis, stretching the graph vertically by a factor of 4, and then translating the graph 5 units to the left. B. reflecting the graph of f(x) in the x-axis, stretching the graph vertically by a factor of 4, and then translating the graph 5 units to the right. C. reflecting the graph of f(x) in the x-axis, stretching the graph vertically by a factor of -, and then translating the graph 5 units to the left. D. reflecting the graph f(x) of in the y-axis, stretching the graph vertically by a factor of 4, and then translating the graph 5 units up. Hint: Compare g(x) =- 410g. (x + 5) to y = alog (b(x - h)) + k
