This mapping shows a functional relationship . when f(x)=4 , what is the value of x? 0. 2. 3. 4.

the answer is b

step-by-step explanation:

The domain consists of a pre image, and the range consists of the image. when we are looking at f(x), we are looking at the range. when we are looking at x, we are looking at the domain. when the range is 4, the x value is 2. 

so, when f(x) is 4, the value of x is 2. 

You have to find the angle i don’t know if i i try

It is 2 out of 8 she will pick green and 3 out of 7 she will pick green but red and green would be 5 out of 5 so 50% chance
