Answer:
16
Step-by-step explanation:
F(x) = x²-4x-5, quadratic function,
Domain (the values if x) is all real numbers.
To find range we should draw a graph or to write an equation in vertex form.
f(x) = x²-4x+4-4-5
f(x) = (x-2)²-9
Point (-2,-9) is the vertex of the parabola, and it is a minimum because a parabola has positive sign in front of x², so it is looking up. Minimum value of y =-9
Range(the values of y) is [-9, ∞)

Answer:</h3>
5 units
<h3>
Step-by-step explanation:</h3>
A point 4 up and 3 over from its original location has moved a distance that can be found using the Pythagorean theorem.
... d² = 4² +3² = 16 +9 = 25
... d = √25 = 5 . . . . units
The given distance of 5.20 would be A.
Replace A with 5.20 to solve for T.
T = 5.20^3/2
T = 11.9 years.
