Question

Use the quadratic function to predict f(x) if x equals 8. f(x) = 25x2 − 28x + 585
f(8) = 1961


f(8) = 2201


f(8) = 2679


f(8) = 1614

Answer 1

i know the answer it is i think

To predict f(x) when x equals 8 we simply substitute.  

So f(x) = 25x2 28x + 585  

 f(8) = 25 (8)^2 - 28 (8) + 585

 f(8) = 25 * 64 - 224 + 585

 f(8) = 1600 - 224 + 585 = 1961

 Hencse f(8) = 1961

Answer 2

hloo friend^_^..___

Q= f(x) = 25x2 − 28x + 585

Solution
________

f(8) = 25*(8)^2 - 28*8 + 585

= 25*64 - 224 + 585

= 1600 - 224 + 585

= 2185-224

= 1961 Ans...


So the correct ans is f(8) = 1961...



I HOPE ITS HELP U MY FRIEND..^_^
