Use the quadratic model y = -4x2 + 8x + 8 to predict y if x equals 100.

ANSWER:

The value of y in is -39192 when x is 100.

SOLUTION:  

Given the quadratic equation is  --- eqn (1)

And we need to predict y when x =100

Let’s use the substitution method to solve this problem.

To get the value of y, substitute the x value in the equation (1)

= -40000 + 808

y = -39192

Hence the value of y is -39192 when x is 100.
