Question

What is the domain and range of 1/-3x+2

Answer 1

denom ≠ 0

therfore solve for x.
which is x = 2/3.

x must therefore be greater than or equal to 2/3.

Answer 2

Wait a minute there.
If the fraction is 1/(-3x + 2), with -3x + 2 as the denominator, then that denominator cannot equal zero.
Which value of x makes -3x + 2 = 0? To find that out, solve -3x + 2 = 0
-3x + 2 = 0
-3x = -2
x = 2/3
So the domain is all values of x except x = 2/3

Answer 3

yep
