When the definition of a function involves a fraction, the function is undefined at any value that would make the denominator of the function is; a) 0
What is an Undefined Function?
A function that is a fraction is said to be undefined when the denominator is equal to zero. If there are variables in the denominator, the point at which the expression in the denominator is zero is the point where that function is undefined.
From the question, we want to know what the value of the denominator of a fraction will be to make that fraction undefined. From the definition above, it is clear that the value would be zero.

When you solve the following equation, solving for the quadratic formula.
The answer is; x=4
Next time pay attention in class.
Answer: Option 'B' and 'C' are correct.
Step-by-step explanation:
Since we have given that
A rocket was fired into the air.
The rocket reached a maximum height of 59 feet at point (3.5,59) as shown in the figure.
And it took the rocket 3.5 seconds to reach its maximum height.
and the rocket landed after 6.9 seconds, So option 'D' is false which states The rocket landed after 34 seconds.
The equation that represents the rocket’s height over time has two solutions is completely false as it has only one solutions.
Hence, Option 'B' and 'C' are correct.
The number of cookies packs needed if the treasurer buys 1 package of brownies bites is 5 packs
<h3>Equation</h3>
- Total attendance = 75 people
- Cookies in each pack = 12
- Brownies in each pack = 15
- Number of cookies pack = c
- Number of brownies pack = b
15b + 12c = 75
If 1 package of brownies is bought
15b + 12c = 75
15(1) + 12c = 75
15 + 12c = 75
12c = 75 - 15
12c = 60
c = 60/12
c = 5 packs
- It is a reasonable value in this context
If 9 packages of brownies are bought
15b + 12c = 75
15(9) + 12c = 75
135 + 12c = 75
12c = 75 - 135
12c = -60
c = -60/12
c = -5 packs
- The value is not reasonable in this context
