Somebody please help me algebra 2 graphing equations!! help me find:1) slope of the initial climb2) domain and range of graph3) equation that represents initial climb4) if it’s a function or not5) which hill is steeper

We will have the following:
1. The slope of the initial clim:
[tex]m=\frac{20-0}{10-0}\Rightarrow m=2[/tex]So, the slope of the initial climb is 2.
2.
*The domain seems to be contained from 0 to infinity.
*The range is contained from 0 to 50.
3. The quation that represents its initial climb wuld be:
[tex]f(x)=2x[/tex]4. We will have that the graph does not represent a function. [Functions do not go back over themselves as it happens in this graph].
5. We would have that the hill that is steeper would be the first one.
