What is the value of the range of the function f(x) =2x2-3x+8 for the domain value3?

Given the function

For the domain value x=3 you should find f(3). With this aim substitute instead x the value 3 into the function expression:

the value of the range f(3) is 17.

Answer

17

Explanation

The range of a function is the value resulting from the possible independent  variable x.  It is the value of y in a function for any given independent variable.

f(x) =2x²-3x+8

When the domain = 3

f(x) = 2(3)² - 3(3) + 8

     = 2×9 - 3×3 + 8

    = 18 - 9 + 8

    = 17

step by step explanation: when u removing the parentheses and combined them that would be : x+3y-x-y=2y
