f(x) = 2
-4x
Step-by-step explanation:
Step 1 :
Given, f(x) = a(x - h)2 + k
Point on the parabola is (3, 6)
Vertex (h,k) = (1,-2)
Step 2:
Substituting the vertex in the equation we have,
f(x) = a(x-1)2 -2
Substituting the point (3,6) in this we have,
6 = a(3-1)2 - 2 => 6 = 4a -2
=> 4a = 8 => a = 2
Step 3 :
Substituting the value for a and the vertex in the given equation we have
f(x) = 2(x-1)2 -2 = 2(x2 - 2x + 1) -2 = 2x2 - 4x
=> f(x) = 2
-4x which is the standard form
I don't think you can solve for x unless they give you what that equation equals (for example 5x+8=7)
I'm pretty sure that is as simplified as it can be

The answer is 1/23 that’s right
In the given problem, it is already given that Randy can walk for a distance of 1/2 a mile in 1/5 of an hour. Now let us first convert 1/5 hour to minutes. this will make the problem a bit easy.
1/5 hour = 1/5 * 60 minutes
= 12 minutes
So
Randy in 12 minutes can walk for a distance of = 1/2 mile
Then
In 60 minutes Randy can walk for a distance of = [1/(2*12)] * 60
= (1/24) * 60
= 2.5
So Randy can walk 2.5 miles in 1 hour.
