Answer:
domain: (-∞ , ∞)
range: (-∞, 2]
Step-by-step explanation:
the domain is the set of values of what the x value can be. This function is parabolic and upside down, it can have a range of x values from - infinity to positive infinity. The function is most likely y=-x^2 +2
range is the output (y values) the function can possibly have. the max is 2 and includes 2 so we use bracket for that. The smallest y value can reach towards negative infinity.

Answer:
B. The other solution to function 
is 
.
Step-by-step explanation:
From Algebra, we remember that quadratic functions of the form 
has solutions of the form:
, where both are complex if and only if 
.
Hence, if one solution of the quadratic function is 
, then the other solution is . The correct answer is B.
Answer: C
Step-by-step explanation: In bracket we subtract 8,5% which is 0.085 from whole amount which is 1. Then the obtained result, we raised to the power of x - wich respresent numbers of years
