Given g(x) = -x – 4, find g(-5).

riadik2000 [5.3K]

The value of g(-5) from the given. function; g(x) = -x – 4 is; g(-5) = 1

<h3>Evaluation of functions</h3>

The given function is;

g(x) = -x – 4

Hence, the value of g(-5) can be obtained by substituting -5 for x in the function as follows;

g(-5) = -(-5) -4

g(-5) = 5 -4

g(-5) = 1.
