I am struggling to evaluate this problem
f(x)=sqrt x+7-5
---------------
Is it sqrt(x)+7-5 ?
Or sqrt(x+7) - 5 ?
Or Sqrt(x+7-5) ?

.

Use parentheses to show where the expression starts and ends
under the square root symbol.

assuming you have
f%28x%29=sqrt%28x%2B7%29-5
f%287%29=
means x=7
f%287%29=sqrt%287%2B7%29-5
f%287%29=sqrt%2814%29-5
f%287%29=-1.26

f%280%29=
f%280%29=sqrt%280%2B7%29-5
f%280%29=sqrt%287%29-5
f%280%29=-2.35
