Question 674595: Let g and f be two functions defined by
g(x)=(-5+x)(2+x)
f(x)=2-9x
for any real number x.
Find g/f(-3) and then find all values that are NOT in the domain of g/f. If there is more than one value, separate them with commas.
g/f(-3)= _________
Values that are NOT in the domain of g/f : ___________
Any help please... I'm stuck and this is my last question of a real important test! Thanks! :)
Answer by ReadingBoosters(3246) (Show Source): You can put this solution on YOUR website!
g(x) = (-5+x)(2+x)
f(x) = 2 - 9x
...
g/f(-3) =
=
...
g/f(x) will be undefined where the denominator = 0
0 = 2-9x
-2 = -9x
=x
Values not in the domain of g/f =
