Answer:
B. subtraction property of inequality
Step-by-step explanation:
Answer:
The correct option is 4.
Step-by-step explanation:
The given function is

Where f(x) is height of the ball and x is the distance.
It is a polynomial function with degree 2. All polynomial functions are defined for all real numbers, therefore the mathematical domain of the function is all real numbers.

Factorize the given function.





Put f(x)=0 to find the x intercepts.

Equate each factor equal to 0.

Therefore at x=52 and -2, the graph of f(x) intersects x-axis. Before x=-2 and after x=52 the values of f(x) is negative. Height cannot be negative, therefore reasonable domain is lie between -2 to 52.
Distance cannot be negative, therefore the reasonable domain must be positive.

Therefore the reasonable domain is
and option 4 is correct.
ANSWER : 9 over 4
or 2 and 1/4
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
*3 over 2 x 3 over 2 is 3/2 x 3/2* << this is for me to remember
Okay so multiplying fractions means for us to multiply across. That means if we line the fractions, we multiply. Like this
3 x 3
----- ----- 3 times 3 is = 9
2 x 2 2 times 2 is = 4
9 over 4 is the same thing as 2 and 1/4 << FRACTION

WHOLE
Hope I helped (:
