Answer:

Step-by-step explanation:

Using the trigonometric identity

sin2x = 2sinxcosx

That is the angle on the right side is half the angle on the left, thus

sinΘ = 2sin( $\frac{1}{2}$ Θ )cos( $\frac{1}{2}$ Θ ) → b

Step-by-step explanation:

The absolute value function is:

y = | x |

Step 1. Function is vertically stretched by a factor of 3:

y = 3 * | x |

Step 2. Shifted two units left:

y = 3 | x + 2 |

Kitty [74]

Answer:

See below

Step-by-step explanation:

Not sure what you are asking....do you want to know what y is when x = -2 and the equation = 6 ?

3 xy^2 + 4x = 6 or is that 3 xy^(-2) + 4x = 6

Could use some serious editing of your question if you are able ....
