I suggest making a quick sketch of
y = -3sinx
and
y = -3sin(2x) + 1
pick critical angles like 30, 45, 60, 90 degrees etc
.In the function f(x), x is replaced with 2x and 1 is added to the function.
f(x)=−3sinx
What effect does this have on the graph of the function?
a. The graph is horizontally compressed by a factor of 2 and shifts up 1 unit
b. The graph is horizontally compressed by a factor of 2 and shifts down 1 unit
c. The graph is vertically stretched by a factor of 2 and shifts up 1 unit*
d. The graph is vertically stretched by a factor of 2 and shifts down 1 unit
