find the value of $f(9)$.\n$y = f(x)$
find the value of $f(9)$.\n$y = f(x)$
Answer
Explanation:
Step1: Identify right segment equation
The right segment passes through $(0,0)$ and has a slope of $1$, so its equation is $y = x$ (valid for $x \geq 0$).
Step2: Substitute $x=9$ into the equation
Since $9 \geq 0$, use $y = x$. $y = 9$
Answer:
$9$
