Question

Graph each function. Find the y-intercept, and state the domain and range.

Please help!!!! Explain and show work please!!!! I'm really stuck on this!!!!

Answer 1

2. In this one , x can take any values from -infinity to +infinity because at every value of x there will be a specific value of y.

So domain of x is all real values.

However for any value of x, y will not be negative or zero , so Range of y will be y > 0. Moreover when x approaches infinity y approaches to 0 but it will not become 0 , so the graph will not touch x-axis. And for x approaching to -infinity y will approach infinity.

4. In this case also, domain of x is all real nos. as it can all real values.

In this case the range of y will not be y > 0 but it will be y > 2. This will happen because when x approaches -infinity then 3^x approaches 0 and y approaches to 2 as a shift of +2 is there so the whole graph will shift towards positive y by 2 units.

Hope this helps. Mark my answer as BRAINLIEST please!!!
