Question

3. The graph of y = -3sin( 2x) is shifted to the left by 30 units and up 5 units. Write the new equation.

Answer 1

is this correct?

The new equation would be (-3)*sin( 2x+30)+5.

Answer 2

is it 30 units or pi/6 ???

Answer 3

30 units

Answer 4

I am not sure ..

Answer 5

@accessdenied, is that correct?

Answer 6

the up is correct.

Answer 7

I think it should be +60 instead of +30
sin(2(x+30)) = sin(2x + 60)

Answer 8

Thank you experiment

Answer 9

So this?

(-3)*sin( 2*x+60)+5

Answer 10

yeah, at least that's what my graph is agreeing with. D:

Answer 11

got it. thanks guys:)
