Your function can be written as
The general fucntion is
Can you see how this now looks like yours?
How do you graph f(x)=13*sin(pi/2X-pi/4)+4? specifically
I understand what each number does in terms of 13= vert stretch, pi/2 is horizontal compression/stretch, pi/4 is horizontal shift right, and +4 is vertical shift up....
But how do you graph it via translating it from the points of a regular sin graph? In terms of radians.
