What is the maximum value of the function?
What is the minimum value of the function?
What is the amplitude of the function?
Select the two transformations that are required to turn the graph of $y=\cos x$y=cosx into the graph of $y=-3\cos x$y=−3cosx.
Vertical dilation.
Horizontal translation.
Reflection across the $x$x-axis.
Vertical translation.
Which combinations of transformations could be used to turn the graph of $y=\cos x$y=cosx into the graph of $y=-\cos x+3$y=−cosx+3?
Consider the two graphs:
$A$A: $y=\sin x$y=sinx
$B$B: $y=\sin x-2$y=sinx−2.
The graph of $y=\sin x$y=sinx has been transformed into the graph of $y=\sin x-2$y=sinx−2.
