Answer:
Step-by-step explanation:
When an equation has no solution there's no true value for x. What we have is a Contradiction, a false answer.
1)The first and the last equation has a true solution in the form:
True
2)The third one has a solution:
True
3) The second one
FALSE
A Contradiction. Then, this one has no solution.

Answer:
The parent sine graph has a range of -1 ≤ y ≤ 1
It crosses the x-axis x = 0° ± 180°n
The maximum points occur when x = 90° ± 360°n and y = 1
The minimum points occur when x = 270° ± 360°n and y = -1
The sketch the graph of function we simply move the graph of
up 2 units.
So this means it will have a range of 1 ≤ y ≤ 3
It no longer crosses the x-axis.
The maximum points occur when x = 90° ± 360°n and y = 3
The minimum points occur when x = 270° ± 360°n and y = 1
