    f(x)=y x= 4 so substitute 4 for x

    put that feller in that there function and you got yourself a nice little output. f[x]=-2x so at x=4 f[4]=-2(4)=??

    just substitute 4 into x... so f(x)= -2(4)= -8

    Why would you divide?

    the function says at a "x" you will have a "y" value that is "=" to -2x. So when x is 4 (x=4) then the y value would be -2(4)=-8
