For the answer to the question above,

From the data given, generate first the quadratic equation which best describe the height of the ball. The quadratic function has a general form of 
f(x) = Ax^2 + Bx 

Substituting the known data,

(1)            148 = A(1^2) + B(1)
(2)             272 = A (2^2) + B (2)
solving for A and  B simultaneously, 

A = -12
B = 160
So the to answer this problem, substitute 6 to x. Thus, after 6 seconds, the height is 528 feet.

Rewrite the function by completing the square. f(x)= x^{2} + x -30f(x)=x 2 +x−30f, left parenthesis, x, right parenthesis, equal
Verizon [17]

Answer:

f(x)= (x+\frac{1}{2} )^{2}-30\frac{1}{4}

Step-by-step explanation:

f(x)= x^{2} + x -30

To re-write the function by completing the square, the procedure is to first

(i)take the coefficient of x

(ii)Divide it by 2 and Square it

Coefficient of x=1

Divided by 2 = 1/2

Square of 1/2 = (\frac{1}{2} )^{2}

Next, we add it to the function and subtract same so that the equation remains balanced

f(x)= x^{2} + x +(\frac{1}{2} )^{2}-(\frac{1}{2} )^{2}-30

Pick each of the squared term and square the sum

f(x)= (x+\frac{1}{2} )^{2}-(\frac{1}{2} )^{2}-30

f(x)= (x+\frac{1}{2} )^{2}-30\frac{1}{4}
