What is the domain of the piecewise function below? -2x+8 if x>3
f(x)= -x^2 if-2 1 if x <-2
A. all real numbers between -2 and 3
B. all real numbers less than -2
C. all real numbers greater than or equal to 3
D. all real numbers

Answer D : All real numbers

Step-by-step explanation:

Notice that all real numbers are covered in the Domain of the piece-wise function:

 union with     union with

That covers the entire Real number line.

phosphate, calcium ion, chloride ion, neon atom

step-by-step explanation:

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
