Homework Statement
Transform the following equation:
X2sin(3x)
1. Stretch vertically by a factor 9
2. Stretch horizontally by a factor 3
3. Shift to the left by a value of 1.2. The attempt at a solution
1. Stretching vertically by a factor 9 gives:
9x2sin(3x)
2. Stretching vertically by factor 3 is done by dividing 3x by 3, so I get
9x2sin(x)3. Shifting one to the left gives (I think I am going wrong here):
9(x+1)2sin(x+1)
Which can be simplified into:
(9x2+18x+9)sin(x+1)But this answer is wrong. Where did I go wrong?
