Question

F(x) = 3x - 8/4x + 20

Answer 1

Instructions....?

Answer 2

Find the domain of the following rational function

Answer 3

what's the domain?

Answer 4

So I assume this is what you have:
\[f(x) = \frac{3x - 8}{4x + 20}\]

Answer 5

Yes

Answer 6

@EvaH47, what are the restrictions on the domain for this function? In other words, what can \(x\) NOT equal?

Answer 7

Not sure. real numbers?

Answer 8

x cannot equal to zero

Answer 9

Is that the answer?

Answer 10

yes that's the question, where is the denominator in your question?

Answer 11

In real numbers, is when u limit the domain by let's say 2/0 therefore the denominator cannot be zero

Answer 12

The denominator is the 4x +20. I am to simplify by dividing

Answer 13

I am so lost.

Answer 14

no, the equation supposed to look like 4x+20 = 0
and from there, solve x

Answer 15

we don't want the division to be zero

Answer 16

ok
