Question 1042528: Provide two different sketches that satisfy the conditions described below.
a) Three cycles of a trigonometric function with a period of 10 and amplitude of 3. The domain of the function is -10 ≤ x ≤20, xER. State the following key features for the function: range, intercepts, maximum/minimum values, sinusoidal axis of symmetry.
Thanks :)

The function must be:
+f%28x%29+=+3%2Asin%28+%28+2%2Api%2Ax+%29%2F10+%29+
When x = 10, 20, 30, etc
( 2*pi*x )/10 = 2pi, 4pi, 6pi, etc.
and these are periods of the sin
-----------------------------
Here's the plot:
+graph%28+400%2C+400%2C+-10%2C+20%2C+-3%2C+3%2C+3%2Asin%28+%282%2Api%2Ax%2F10%29+%29+%29+
The range is:
+-3+%3C=+f%28x%29+%3C=+3+
-------------------
The x-intercepts are:
-10, -5, 0, 5, 10, 15, 20
The y-intercept is +y+=+0+
-------------------------
The maximums are at:
( -7.5, 3 )
( 2.5, 3 )
( 12.5, 3 )
The minimums are at:
( -5, -3 )
( 5, -3 )
( 15, -3 )
---------------------
The sine function is an odd function which
means that +f%28+-x+%29+=+-f%28x%29+
