If x is zero then you must replace x with zero and use the rules of PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction) to solve
7 + (-4(0)^2)
7 + (-4(0))
7 + 0
7
If x is 0 then the expression equals 7

Measures of spread (also called measures of dispersion) tell you something about how wide the set of data is. There are several basic measures of spread used in statistics. The most common are:
1.) The range (including the interquartile range and the interdecile range),
2.) The standard deviation,
3.) The variance,
4.) Quartiles.
I hope this helps.
