Question

Evaluate f(x)=-x^2+1 for x=-3

Answer 1

For this case we have a function of the form
`y = f (x)`, where:

`f (x) = - x ^ 2 + 1`

We must evaluate the function for
`x = -3`

Then we have to replace:

`f (-3) = - (- 3) ^ 2 + 1\\f (-3) = - 9 + 1`

Different signs are subtracted and the sign of the major is placed:

`f (-3) = - 8`

ANswer:

`f (-3) = - 8`
