In this exercise we have the following equation of a parabola:
So our goal is to find the x-intercepts. We can find this setting 
, so:
Taking 2 as common factor:
Hence this is a Non-perfect Square Trinomial. To factor out this, let's choose two numbers such that:
- The sum is -6
- The product is 5
Those two numbers are:
Because:
So this equation can be written as:

To calculate the range of the given function we first need to calculate for the inverse of the function;
y=sqrt(x)-5
this can be written as:
y+5=sqrt(x)
From the above equation we can conclude that we can get the squaring of all values of x such that:
x≥-5
otherwise we won't get any square root since the square roots of negative numbers will complex numbers;
thus we conclude that the range of the function is {y∈R: y≥-5}
since -4 is included in this set, then our answer is option [A]
