For the function 2x-x^2
find f(4)-f(2) / (2)
I got -8-0/2 so my final answer was -4?
it appears so.
Thank u :)
To find the value of f(4) for the function 2x - x^2, we substitute x = 4 into the function.
f(4) = 2(4) - (4)^2
= 8 - 16
= -8
Next, we find the value of f(2) for the same function:
f(2) = 2(2) - (2)^2
= 4 - 4
= 0
Now, let's calculate f(4) - f(2) / 2:
f(4) - f(2) / 2 = (-8 - 0) / 2
= -8 / 2
= -4
So, your final answer of -4 is correct.
