Name all the values of x that are not in the domain of f(x)=2-x^2/x+5.
Answer: x=-5
correct. Division is not defined by zero.
I thought so. Thanks
To find the values of x that are not in the domain of the function f(x) = 2 - x^2 / (x + 5), we need to identify any values of x that would result in division by zero.
In this case, the function has a fraction with x + 5 in the denominator. Division by zero is undefined in mathematics, so we need to find the value(s) of x that make the denominator equal to zero.
To do this, we set x + 5 = 0 and solve for x:
x + 5 = 0
x = -5
Therefore, the value x = -5 makes the denominator of the function equal to zero. Thus, x = -5 is not in the domain of the function f(x).
