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)

 

[nycmathguy]

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

Does your reply mean I got it right?

 

[MathLover1]

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

 

[nycmathguy]

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?

 

[MathLover1]

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

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

 

[nycmathguy]

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....
