Answer:
Isamar
Step-by-step explanation:
We are given that a function
is a translation of the graph
Karla believes that the graph of g is '' to the right '' of the graph of f.
Isamar believes that the graph of g is ''to the left'' of the graph f.
When we draw a graph then we can see that
The coordinates of vertex of f are (0,0).
The coordinates of vertex of g(x) are (-3,0).
When x shift 3 units towards left then we get g(x)
Therefore, Isamar is correct.
Answer:
9. b. sometimes true
10. a. always true
Explanation:
9. Any function will have an inverse relation. This question is not specific as to whether that inverse <em>relation</em> must be a <em>function</em>. We will assume that that is the intent.
The attached graph shows a cubic function with an inverse function (green), and another without (red).
A cubic function will have an inverse <em>function</em> sometimes.
____
10. As stated above, any function will have an inverse <em>relation</em>.
A linear function will have an inverse relation always.
__
The graph shows a linear function with an inverse function (green), and one that has an inverse <em>relation</em>, but not an inverse <em>function</em> (red).
