Question

evaluating functions use the function f(x) = 3x + 9 to answer the following questions evaluate f(0): f(0) = determine x when f(x) = -6 x =

Explanation:

Step1: Evaluate $f(0)$

Substitute $x=0$ into $f(x)=3x+9$:
$f(0)=3(0)+9=0+9=9$

Step2: Solve for $x$ when $f(x)=-6$

Set $3x+9=-6$, isolate $3x$:
$3x=-6-9=-15$

Step3: Solve for $x$

Divide both sides by 3:
$x=\frac{-15}{3}=-5$

Answer:

$f(0)=9$
$x=-5$
