Question

If f (x) =3x^2-x, find f (-2)

Answer 1

f (-2) = 3*(-2)^2
3*4= 12

Answer 2

The formatting of this question is unclear. Is the original question supposed to read
`f(x)=3x^(2)-x` or
`f(x)=(3x)^(2)-x` assuming the former:


`f(x)=3x^(2)-x`

`f(-2)=3((-2)^(2))-(-2)`

`f(-2)=3(4)+2`

`f(-2)=12+2`

`f(-2)=14`
