when f(0) mean if x is equal to 0......that mean 8-2(0) ^2
which lead to 8-0 b/c -2 times 0 is 0 and square that is still 0, there fore iit is 8-0......
that mean f(0) is equal to 8

f( 0 ) = 8 - 2(0)^2
= 8 - 0 = 8

Substitute 0 for x.
f(0) = 8 - 2(0)^2 = 8 - 0 = 8

Just plug the 0 into the right side of the equation (i.e. replace the x on the right side with a 0, and calculate the result).
I'm sure you can figure out f(0), but to show you how it's done, here's how to figure out, for example, f(3):
f(3) = 8 - 2(3)^2
f(3) = 8 - 2 x (3)^2
f(3) = 8 - 2 x 9
f(3) = 8 - 18
f(3) = -10
Good luck!
(you did want to see an easy way to solve it, but didn't want us to actually solve it, right?)

just substitute x with 0.
f(0)=8-2(0)^2

thats pretty easy. f(0) means that you plug in 0 for all of the "x" variables. so that leads us to f(0) = 8 - 2(0)^2. 0^2 would be 0, so we go to f(0)= 8-2(0). one of the properties of 0 is that everything multiplied by 0 = 0. so we go to f(0)= 8-0. 8-0 obviously equals 8, so f(0)= 8
~STEPS~
f(0)= 8-2(0)^2
f(0)= 8-2(0)
f(0)= 8-0
f(0)= 8
hope this helped.

If you have f(x) = 8 - 2x^2, find f(0)
First: replace "0" with the "x" variable in the function.
f(x) = 8 - 2x^2
f(0) = 8 - 2(0)^2
f(0) = 8 - 2(0)(0)
f(0) = 8 - 2(0)
f(0) = 8 - 0
f(0) = 8

f(0) means that x = 0
f(0) = 8 - 0
f(0) = 8
