Answer:
-----> vertex form
-----> standard form
Step-by-step explanation:
we know that
The equation of a vertical parabola in vertex form is equal to
where
(h,k) is the vertex of the parabola
In this problem we have
substitute the values and solve for a
the equation in vertex form is equal to
Find the equation of the parabola in standard form
we know that
the equation of the parabola in standard form is equal to
we have
convert to standard form
Isolate the x. note the equal sign, what you do to one side, you do to the other.
Multiply 0.4 to both sides
x/0.4(0.4) = 0.6(0.4)
x = 0.6(0.4)
Simplify
x = 0.24
0.24 is your answer for x
hope this helps
I don't think this is possible...
But if you mean 9 then the root is 3
