Graph y=-2^x+1+3. Then find the domain and range
It's a log graph I'm assuming
Nvm! I graphed it. I just need the domain/range
Are you familiar with what the parent function look like?
What is it?
Can you graph it? ^_^ |dw:1439768317409:dw|
|dw:1439768409796:dw| Good! :)
What happens when the function 2^x is multiplied by negative 1 (-1)?
I still don't know how to find the range of the function I posted?
and what happened when the function is added by 4? Does it shift up or down?
From the graph you drew, what is the range and domain? Any guesses?
Hint: The domain is where the function passes the x-values The range is where the function passes the y-values. Is there any restriction with the domain or range in this graph?
d=all real numbers
What about the range?
hmmm...I dont know.
Am I wrong?
The range is all real numbers except y=0. This is the range for the function y=2^x, not for y=2^x+4 (the function you were given).
Now. From the graph you were given. Are there any vertical shifts?
And does the graph flip ?
not from what i can see
From the graph you've shown me. Did it flip and vertically shifted compared to the parent function you drew: y=2^x?
Yes. What is the range?|dw:1439769088312:dw|
All real #'s except zero, right?
But doesn't the graph pass y=0?
is that right y>4 or would it be y<=4
As you can see from the graph, it passes all the y-values below 4. And all the y values below 4 are less than y. So y<4.
yay! Thanks so much :)
