# Dynamic Credential Method 1

	if ($who.substring($who.length-2, 2) -eq "-a"){$username=$who;}
    else {$username=$who+"-admin";}
#$password = Read-Host -Prompt "Input the password for account $username" -AsSecureString
$password=convertto-securestring "PASSWORD" -AsPlainText -Force
$cred = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $username,$password	#To be Invoked with switch -Credential
$elevate = New-PSSession -ComputerName localhost -Credential $cred	#$To be Invoked with switch -Session

# Local function
function localFunc ($x, $y)
{
    ping google.com
}

Invoke-Command -Session $elevate -ScriptBlock { 
    param( $x, $y, $importedFunc)

    # Import the function from the variable inside parameters
    [ScriptBlock]::Create($importedFunc).Invoke($x,$y)

} -ArgumentList $xVariable, $yVariable, ${function:localFunc}
