Find the maximum value of y = -2(x - 4)2 - 6. a) -6 b) -4 c) -2 d) 4

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.

(4,-6)

Hope you get it!

the answer is 31.27mph

the answer would be c:   ax + b = ax + c
