Question

f(x) = 12x2 - (14x + 3), what is the value of f(8).

Answer 1

Answer:

I think , f(x) = 12x² -14x-3 .

f(8) => 12(8²)-(14*8)-3 ==> 656

Answer 2

Answer:

653

Step-by-step explanation:

Given:- $F(x) = 12x^{2} -14x - 3$

To Find:- Value of F(8)

Solution:-

$F(x) = 12x^{2} -14x - 3$

Putting x = 8 in above equation, we get

$F(8) = 12(8)^{2} -14* 8 - 3$

        $= 12 * 64 - 112 - 3$

        $= 768 - 115$

         $= 653$

Therefore, F(8) = 653.
