A area and B radius are the answers
Answer:
The answer is A.
Step-by-step explanation:
In this kind of exercise the usual way to solve it is s kind of trial an error. We evaluate f(x) in the given values of x and check if it corresponds with the values of f(x) in the table. If only one of the calculations does not correspond we dismiss the function.
Let us start our analysis from D. to A.
D. In this case f(x) = x-1, then f(-3) = -3-1=-4, and the result does not correspond to the values of the table (recall f(-3)=-1).
C. The same idea: we have f(x)=x-2, then f(-3)=-3-2=-5, and the result does not correspond to the values of the table (recall f(-3)=-1).
B. Here f(x)=3x, then f(-3)=3*(-3)=-9, and the result does not correspond to the values of the table (recall f(-3)=-1).
A. Now f(x)=x+2, then f(-3)=-3+2=-1, and the result does correspond to the values of the table (recall f(-3)=-1). So, we need to check the next values of the table:
f(0)=0+2=2, f(3)=3+2=5 and f(6)=6+2=8.
As all the values are equal to those in the table, we conclude that A. is the correct answer.

Evaluating the function,f(x) = –2x² – 3x + 5 for x = -3, we would have: f(-3) = -4. (option B).
To evaluate a function, plug in the given value of the input (x) and simplify.
Thus:
f(x) = –2x² – 3x + 5
Substitute x = -3 into the function
f(-3) = –2(-3)² – 3(-3) + 5
f(-3) = -2(9) + 9 + 5
f(-3) = -4
Therefore, evaluating the function,f(x) = –2x² – 3x + 5 for x = -3, we would have: f(-3) = -4. (option B).

Answer:
Step-by-step explanation:
We have been given that a certain function is an inverse proportion. We are asked to find the formula for the function if it is known that the function is equal to 12 when the independent variable is equal to 2.
We know that two inversely proportional quantities are in form , where y is inversely proportional to x and k is constant of variation.
Upon substituting and in above equation, we will get:
Let us solve for constant of variation.
Now, we will substitute in inversely proportion equation as:
Therefore, the formula for the given scenario would be .
