Walk on the graph from the right of x=3, towards it, what y value do you end up at ? |dw:1439662480541:dw|
nope, the exact value at x=3 doesn't matter whats the y value as you "approach" x=3 from the right ?
Notice that the graph is staying constant at y = -3
how can you say that bro ?
look at the point on graph the dot point right front of y=7
Is the answer -3? @sohailiftikhar @ganeshie8
-3 is correct
@sohailiftikhar for limit, the actual value of function at the particular value doesn't matter all it matters is whatgoes on around it..
Could you help me with another one? @ganeshie8
@ganeshie8 ^ (:
Would the limit be 3 because when you approach x = 3 from the right, y=3?
You got it!
And for this one: Find limit as x approaches two from the left of f of x. and limit as x approaches two from the right of f of x..
Would the answer be: -2;3 or 3;-2 ? @ganeshie8
whats the limit from right side ?
Oh, the right side would be the bottom line? Which would be the first limit listed? So, -2; 3?
limit from left side is 3 limit from right side is -2
Yes, that is understood. Which one comes first, though. I'm between: 3; -2 or -2; 3
which one was asked first ?
`Find limit as x approaches two from the left of f of x. and limit as x approaches two from the right of f of x..`
no ganish bro -3 is not correct answer look at graph what the minimum value of y you have give it's -1 and now the value of y increasing from -1 to higher values take a look on graph again
so the answer should be \[y \ge-1\]
Yes that one @ganeshie8
@sohailiftikhar That's not an answer choice.
so what are the choices can you please tell me i'm asking about first question
