Ration expressions cause excluded values wherever the denominator equals zero.
So, for any expression like
-5 is an excluded value if
For example, the simplest one would be
In fact, if you try to evaluate this function at -5, you'd have
which is undefined, and thus you can't evaluate the function, and thus -5 is an excluded value.
Answer:
Step-by-step explanation:
-4|-2x+6|=-24 divide both sides by -4
|-2x+6|=6 rewrite twice
-2x+6=6 and -2x+6=-6
-6 -6 -6 -6
-2x=0 -2x= -12 for both equations divide both by two so...
x=0 x=6 then check it
