The red parabola shown is the graph of the equation ay2+by+c=x. Find a+b+c.
very need help im lostEach tick mark on the graph is one unit.
The vertex of the graph is (5,-4), so the equation of the parabola is
x = -(y + 4)^2 + 5
= -y^2 - 8y - 16 + 5
= -y^2 - 8y - 9.
a + b + c = (-1) + (-8) + (-9) = -18.
thanks!
