思路分析
When comparing the parent graph y = sec(x) with y = sec(x + π/4), recall that a horizontal shift occurs by the amount inside the argument with the sign reversed. Here, the graph is transformed by shifting left by π/4 because the expression x + π/4 moves the input to the left on the x-axis. Option analysis: - Phase shift π/4 units t......Login to view full explanation
