Question

Evaluate the function.
ƒ(x) = −x² − 4x – 12
Find ƒ(-7)

Answer 1

Given ~

`\tt \: f(x) = - {x}^(2) - 4x - 12`

`\:`

put the value of x = -7 in given function ~

`\tt \: f( - 7) = - ( { - 7})^(2) - 4( - 7)- 12`

`\:`

`\tt \: f( - 7) = - 49 +28 - 12`

`\:`

`\tt \: f( - 7) = - 21 - 12`

`\:`

`\underline{ \boxed{ \tt \red{ f( - 7) = -33}}}{ \green ✓}`

`\:`

hope helps ~
