f%28x%29=sqrt%28x%2B9%29%2B6
f(-9)=6
f(7)=10
f(x-9)=sqrt%28x%29%2B6

f%28x%29=sqrt%28x%2B9%29%2B6
f%28-9%29=sqrt%28x%2B9%29%2B6
f%28-9%29=sqrt%28%28-9%29%2B9%29%2B6
f%28-9%29=sqrt%280%29%2B6
f%28-9%29=6

f%28x%29=sqrt%28x%2B9%29%2B6
f%287%29=sqrt%28x%2B9%29%2B6
f%287%29=sqrt%287%2B9%29%2B6
f%287%29=sqrt%2816%29%2B6
f%287%29=4%2B6
f%287%29=10

f%28x-9%29=sqrt%28x%2B9%29%2B6
f%28x-9%29=sqrt%28x%2B9%29%2B6
f%28x-9%29=sqrt%28%28x-9%29%2B9%29%2B6
f%28x-9%29=sqrt%28x%29%2B6
