Approximate Values of x...2

Section 2.7
Question 60



See graph below.




Part (a)

For y => 1, x = 2.

Part (b)

For y ≤ 0, x = -2.

 

or y ≤ 0, x = 0 (note that the graph passes through origin)

 

Does your reply mean I got it right?

 

not this: For y ≤ 0, x = -2. this is what my replay was in attempt to tell you that x=-2 is incorrect

 

So, x = -2 is wrong. What is the correct answer?

 

x = 0 (note that the graph passes through origin)

 

Ok. Not a big deal. Answering this particular question right or wrong does not reduce me as an amateur math guy. Moving on....
