Y=-2(x-4)^2-6

The -6 makes it shift from origin(0,0) to (0,-6)

Then the -4 inside with x, makes it shift to the right by for, so the center would be now instead of (0,0), (4,-6).

As it has a negative A factor, it is a parabola open downwards, so the center is the maximum value.

Answer: (4,-6)

Hope you get it!

Find all solutions to the equation. 7 sin2x - 14 sin x + 2 = -5

Alenkinab [10]

7sin²x-14sinx+2= -5
7sin²x-14sinx+7=0
7(sin²x-2sinx+1)=0
sin²x-2sinx+1=0
(sinx-1)(sinx-1)=0
sinx-1=0
sinx=1
$x= \frac{ \pi }{2} +2n \pi$ where n is an integer
