    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 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?

    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).

    Correction: y=-2^x+4

    Now. From the graph you were given. Are there any vertical shifts?

    From the graph you've shown me. Did it flip and vertically shifted compared to the parent function you drew: y=2^x?

    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.
