How to compare numbers in function in bash

Question

I am trying to compare two numbers in bash, but I want it to be in a function and then return with Passed or Failed

So far I have this

myfunc(){
if ["$val1" -eq "$val2"]; then 
   echo "Passed"
else 
   echo "Failed"
}

echo "$myfunc"

The desired output would be if i have val1 = 2 and val2 = 2, they are equal thus it will return

Passed
