1 and 2 are corresponding angles meaning if they are equal but on opposite sides. If you now for example angle 1 = 20 , 2= is also 20. This is helpful to know if you want to solve for x on one of these angles

For what value of \$x\$ is the function \$\\frac{1}{x-2}\$ not defined?

natima [27]

for the value of $x=2$ we have the function f(x) = 1/(x-2) or $f(x)=\frac{1}{x-2}$ as undefined or not defined .

Step-by-step explanation:

Function undefined: A function is undefined when it gives results which are not defined for example , infinity .

Here we have , Function f(x) = 1/(x-2) or $f(x)=\frac{1}{x-2}$ . We need to find a value of for which this is not defined . Let's find out:

We can clearly see that it's a fractional function with numerator as 1 and denominator as x-2 . For a fractional function to be undefined it's denominator must be zero i.e. x-2 = 0 or $x-2=0$

⇒ $x-2=0$

⇒ $x-2+2=0+2$

⇒ $x=2$

Therefore, for the value of $x=2$ we have the function f(x) = 1/(x-2) or $f(x)=\frac{1}{x-2}$ as undefined or not defined .
