what number is excluded from the domain of the function y=5/x-3? please help me!
a. 3
b. Not Here
c. -3
d. 5
I assume you meant
y = 5/(x-3)
when x = 3, we are dividing by zero
so x ≠ 3
What does this have to do with geometry?
To determine the number excluded from the domain of the function y = 5/(x - 3), we need to identify any value of x that would make the denominator (x - 3) equal to zero.
If the denominator is zero, it would create an undefined value in the function because division by zero is undefined in mathematics. Therefore, x - 3 must not equal zero.
To find the excluded number, we solve for x in the equation x - 3 = 0:
x - 3 = 0
x = 3
Hence, the number excluded from the domain is x = 3.
Therefore, the answer is a. 3.
