So if we want to convert the given graph into a lager and make the equation well, the first thing we can do is look at our point. So we know that we know that at X is equal to at X is equal to one. Y is equal to zero. And we know that at X is equal to five. Why is equal to one? And so we know that we have some value of of a Here is our constant. So we know a to the why a to the y has to equal to x and so so if we have a to the y Well, then ate a of zero is equal to one. So that really doesn't tell us anything because any value to the to the zero gun will give us one. But A to the one gives us five eight to the one gives us five. And so we know that our A value has to equal to five. So now that we know is equal to five. Well, then are our function here is is wise equal to log based five of X And so this is this is our solution here
