Answer:
Step-by-step explanation:
You start noticing that for x = 9 g(x) =0, and for x= -7 the function isn't defined.
That splits the number lines in 3 areas: x<-7; -7<x<9, and x>9. (notice the strict inequalities since we already discussed the breaking points.
Let's try a point in each interval, namely, since i like the values, -10, 0, 10.
We have all the informations we need. The value we need are
Answer:
D.
Step-by-step explanation:
f(x) =
g(x) = 2x + 3
(x) = 'f' divided by 'g'
Substitute.
x cannot be - because that would create a zero in the denominator.
That's a no-no.
It makes it 'undefined'
