Answer:
Step-by-step explanation:
Recall the vertex form of a quadratic equation:
Where (h,k) is the vertex.
We are told that the vertex is (0,0). Therefore:
Simplify:
So, to finish the equation, we need to find a.
We know that a point is (2,1). Thus, substitute 1 for f(x) and 2 for x:
Square:
Divide both sides by 4:
So, our a value is 1/4.
And we can thus complete our equation:
And we are done :)

Answer:
The value of b = -2.7
Step-by-step explanation:
Given
As the equation is given by
To determine
Solve the equation for b
Given the equation
switch the sides
Add 2.3 to both sides
Simplify
Therefore, the value of b = -2.7
