So here we are told, this is the graph of y is equal to, so we have The key here is that weĬan approximate solutions to equations through graphing. You would see that x is slightly different than x equals four. And if you had a graphing calculator that could really zoom inĪnd zoom in and zoom in, you would get a value, Is that equal to five?" Let's see, three to the fourth is 81. That actually work out? "3/2 to the fourth power, If you wanted to, youĬould try to test it out. And we can see it, at least over here, it looks like x is roughly equal to four. And so we could lookĪt where they intersect and get an approximate sense Y-value for that x-value in both of these, well then that means that 3/2 to the x is going to be equal to five. Here is if we can find the x-value that gives us the same y-value on both of these equations, well that means that those To the right-hand side, we get y is equal to five. To the left-hand side, we get y is equal to 3/2 to the x power, which is what they originally give us, the graph of that. We could set y equals to each side of it. That is we could take each side of this equationĪnd set them up as a function. And this gives us a hint,Īnd especially because it's, they want us to find anĪpproximate solution, that maybe we can solve this equation or approximate a solution to Try to do this on your own before we work on this together. ![]() ![]() Use the graph to findĪn approximate solution to 3/2 to the x is equal to five. Told, this is the graph of y is equal to 3/2 to the x.
