Step-by-step explanation:
Answer: Option B.
Step-by-step explanation:
For this exercise it is important to remember that, by definition, a relation is a function if and only if each input value has an unique output value.
The input values are the values of the variable "x" and the output values are the values of the variable "y".
You can observe in the table shown in the picture, that the input value -2 has two different output values:

Notice that the input vale -1 has two different output values too:

Therefore, based on this, you can conclude that the information given in the table is a relation but not a function.
Answer:
3619.11 cubic inches
Step-by-step explanation:
volume of a cylinder is 
diameter is 16 in, so radius (r) is 8 in
plug in values:
cubic inches
Answer:
Minimum value of f(x) = -1.
Step-by-step explanation:
We convert it to vertex form:
x^2 - 6x + 8
= (x - 3)^2 - 9 + 8
= (x - 3)^2 - 1
The minimum value occurs when (x - 3)^2 = 0 because a square has a minimum value of zero ( it cannot be negative for real values of x).
So the function has a minimum value of -1.
Answer:
Step-by-step explanation:
Apply the exponent to the innermost parentheses.
(2r²t)³ = 2³(r²)³t³ = 2³r⁶t³
