what is the excluded value of the function?
y = 4/(9x – 45)
• –5
• 0.2
• 5
• –0.2
if x = 5, the denominator is zero and the function is undefined and x = 5 is excluded from the domain.
Like I said before when I had to guess what the question was :)
Sorry, and you are appreciated.
No problem. You are welcome :)
To find the excluded value of the function, we need to identify the values of 'x' for which the function is not defined. In this case, we have the function y = 4/(9x – 45).
The function is not defined when the denominator 9x – 45 equals zero. To find this value, we solve the equation:
9x – 45 = 0
Adding 45 to both sides:
9x = 45
Dividing both sides by 9:
x = 5
Therefore, the excluded value of the function is x = 5.
