Answer:
Step-by-step explanation:
Hint: 1- 2sin²x = Cos 2x
LHS = 1 - 2Sin² (π/4 - Ф/2)
= Cos 2 *(π/4 - Ф/2)
= Cos 2*π/4 - 2*Ф/2
= Cos π/2 - Ф
= Sin Ф = RHS
Answer:
D.No solution
Step-by-step explanation:
These two function are parallel (same slope) , so they would never intersect
The inverse of this function is y = x - 
You can find the inverse of any function by switching the x and y values and then solving for the new y value. Once you've done that, what will be left over is the inverse function.
y =
----> Swap x and y
x =
-----> Subtract 3/4 from both sides.
x -
= y ----> rearrange to appropriate order
y = x - 
And that is your inverse function.
