Find the domain of f/x)=7x/x-3 need

The domain of this function is all real numbers such that x does not equal 3.

We can tell this by looking at the equation for one of two things. The two things that typically disrupt a domain are dividing by zero and taking a square root of a negative. Since there are no square roots, we are only concerned with dividing by zero. So, we take the denominator and set it equal to 0.

x - 3 = 0

x = 3

This means that 3 is the value that makes the denominator 0 and therefor is the only x value we cannot use.

for the first question it would be the second answer for the second question it would be the third answer and for the third question it would be the first answer

step-by-step explanation:

a = 11 : 4

b = 38

c = 1 for every 6
