Answer:
The horizontal line test is used to determine if a functions inverse will be a function. You will compose the functions (that is, plug x into one function, plug that function into the inverse function, and then simplify) and verify that you end up with just "x". Here's what it looks like: Determine algebraically whether f (x) = 3x – 2 and g(x) = (x + 2)/3 are inverses of each other.
Use the horizontal line test to determine if a function is a one-to-one function.
If ANY horizontal line intersects your original function in ONLY ONE location, your function will be a one-to-one function and its inverse will also be a function.
hope this helps

Step-by-step explanation:
Answer:
<em>There are </em><em>70</em><em> students only in chorus.</em>
Step-by-step explanation:
Total number of students is 250
Out of 250, 180 students took band.
And 60 took band and chorus, i.e this is the intersection of the 2 groups.
The Venn diagram is attached below.
So, the number of students who took only band = 180-60 = 120
Total number of students or sum of the 3 regions is 250.
So, the number of students who took only chorus = 250-180 = 70
