How do you graph # y=4cos(2x-1)+3#?
1 Answer
So features of graph
Amp:4
Period:
Max:7
Min:-1
graph{4cos(2x-1)+3 [-10, 10, -5, 5]}
Explanation:
Translation form of sine is
A~ Vertical stretch/Amp, y values get stretched by A
B~ Horizontal strech/Period, x values get stretched by
C~ Horizontal translation/Phase shift, x values move over by C
D~ Vertical translation, y values up by D
So we know that if we put it in translation form it looks like
So we know that the original
Amp:1
Period:
Max: 1
Min: -1
graph{sin(x) [-8.89, 8.886, -4.446, 4.446]}
So
So
So
So features of graph
