Question

What is the range of the function `y=-2sin(2x+pi)-4`?

Answer 1

Range: y such that `-6 <= y <= -2`

Explanation:

...The sine of any quantity varies between -1 and 1. That's all you need to know about the quantity in parenthesis `(2x+ pi)`

When `sin(2x + pi) = -1`, `y = (-2)(-1)-4 = 2 -4 = -2`

When `sin(2x + pi) = 1`, `y = (-2)(1) - 4 = -6`

GOOD LUCK
