HELP ME NOWWW ASAP THIS IS DUE TOMORROW PLSSSS HELP AND STOP SCROLLING!!!!!

Answer: b. f(9)=10
c. f(x-7)=[tex]\sqrt{x}[/tex]+6
Step-by-step explanation:
Good job! You got the first one right! :)
b. f(9)=(9+7)^1/2 + 6
f(9)=16^1/2 + 6
f(9)=4 + 6
f(9)=10
c. f(x-7)=(x-7+7)^1/2+6
f(x-7)=x^1/2+6
f(x-7)=[tex]\sqrt{x}[/tex]+6
