Answer:
The x-intercepts of the graph of the function are -9 and 4
Step-by-step explanation:
- factor the function f(x)=x²+5x-36
- f(x)=(x+9)(x-4)
- x = -9, 4
Answer:
1/2 times 1/3
Step-by-step explanation:
Answer:
y = 14
Step-by-step explanation:
move 5y over to the left and you should get -2y +6=-18. subtract 6from both sides and you will now have -2y=-24. divide bothe sides from -2 and you will get y=14

Answer:</h2><h3>b. n is odd</h3><h2>
Step-by-step explanation:</h2>
In this problem, we assume that 
is a whole number. The definition of inverse functions tells us that a function 
has an inverse function if and only if the function is one-to-one, that is, if there is no any horizontal line intersecting the graph of at more than one point. This only happens if is odd. This is called the Horizontal Line Test for Inverse Functions. So let's take two examples:
FIRST:
Since n is even, an horizontal line will pass through two points as indicated in the first figure below.
SECOND:
Since n is odd, an horizontal line will pass through just one point as indicated in the second figure below.
