f(x)=4^2,-1/x^2, find (-2)

Is f (x) = 4^2 - 1/x^2? Can you verify if f(x) is correct

I think an x is missing.

find f(-2)

that is ok. Is f(x) correct

4x^2-1/ x^2, find f(-2)

Is f(x) = 4x^2 - 1/x^2?

f (x) = 4x^2 - 1/x^2?

f(-2) = 4 * (-2)^2 - 1/(-2)^2

= 4*4 - ( 1/4)

= 16 - (1/4)

= (16*4 -1)/4

= 63/4

Please let me know if you have any other questions and best me if you are satisfactory.

Thanks
