QuestionEvaluate $f(x)=-2x-3$ at $x=-3$ . What is $f(-3)$ ?

Studdy Solution

STEP 1

Assumptions1. The function is $f(x) = -x -3$ . We need to find the value of the function when $x = -3$

STEP 2

To find the value of the function at a given point, we substitute the given value into the function. In this case, we substitute $x = -$ into the function $f(x) = -2x -$ .
$f(-) = -2(-) -$

STEP 3

Now, we simplify the expression by multiplying $-2$ and $-3$ .
$f(-3) =6 -3$

STEP 4

Finally, we subtract $3$ from $6$ to find the value of the function at $x = -3$ .
$f(-3) =6 -3 =3$ So, $f(-3) =3$ .
