Answer and Step-by-step explanation:
We are not given the function in question, but in order to explain, will form a function. Suppose f(x) = 3x + 2.
If f(x) = 17, then
3x + 2 = 17, to find the value of x, we have solve for x in the equation.
3x = 17 – 2
3x = 15
x = 5
This is the method that can be used to solve problems of this nature.
Answer:
range {1,3,-3,4,1} yes that is it
-3 =-2x - 7
Add 7 to both sides
4=-2x
Divide by -2
-2 = x
The formula of an area of a circle:

r - a radius
We have r = 14m. Substitute:

If you want an approximate area, you can accept 
Then:
