QuestionFind the value of the function $f(x)=4x-9$ at $x=3$ . What is $f(3)$ ?

Studdy Solution

STEP 1

Assumptions1. The function is defined as $f(x) =4x -9$ . We need to find the value of the function at $x =3$

STEP 2

To find the value of the function at $x =$ , we substitute $x =$ into the function.
$f() =4 \cdot -9$

STEP 3

Perform the multiplication.
$f(3) =12 -9$

STEP 4

Subtract9 from12 to find the value of the function at $x =3$ .
$f(3) =3$ So, $f(3) =3$ .
