Question

For f(x) = -x-4, evaluate the function if the value of x is –3. |

Answer 1

The given function is,

$f(x)=-x-4$

So in order to find the value of the function , when x = -3, we have to put -3 in the place of x in the above equation.

That is,

$f(-3)=-(-3)-4=3-4=-1$

Thus, the value of the function is -1 when x is -3.
