Graph the equation.
1 answer:
9514 1404 393
Answer:
see attached
Step-by-step explanation:
Sometimes the quadratic is easier to graph if written in vertex form.
y = -x^2 -6x -3
= -(x^2 +6x) -3
= -(x^2 +6x +9) -3 +9
= -(x +3)^2 +6
This is a parabola that opens downward, with its vertex at (-3, 6). Unlike the one shown in the graph already, its scale factor is 1, so it will appear narrower than the one given with the problem statement.

Answer:
f(x) = -8(4)x
Step-by-step explanation:
The reflection of the point (x,y) across the x-axis is the point (x,-y).
Having said this, to reflect the function y=g(x) = 8(4x) over the x-axis, we just need to evaluate the equation in the point: (x,-y).
y = 8(4x) ⇒ -y = 8(4x) ⇒ y = -8(4x)
Then f(x) = -8(4x)
