Answer:
A. f(x)= -(x-3)^(2)-2
Step-by-step explanation:
graphing the parabola, using the direction, vertex, focus, an axis of symmetry, we see that the direction it opens is down, like the picture shows. The vertex is at (3, -2), focus is (3,-9/4), axis of symmetry is x=3, and the directrix is y = -7/4 just as the picture shows. Therefore, A is the correct answer.
Hope this helps!!

squares have 90 degree angles and half of that is 45
Answer:
4x = 3(x - 3).
Step-by-step explanation:
2^4x = 8^(x-3)
Now 8 = 2^3 so:
2^4x = 2^3(x - 3) so
4x = 3(x - 3)
Answer:
x = -4
Step-by-step explanation:
x= 3 is a parallel to y axis. So a parallel line to x = 3 must be parallel to y axis.
A line parallel to y axis has a generic equation: x = h. We know that the line passes to the point with has x coordinate = -4
So the equation is x= -4
