So far, you already know what the graph of the parent sine function,

**y = sin(x)**, looks like. In this applet below, you are given a graph of the function**y = a sin(x) + d**. As you already know, the values "a" & "d" both affect the graph parent sine function**y = sin(x)**. Your task here: Given the graph of**y = a sin(x) + d**, determine the parameters "a" and "d".*Hint: The dashed horizontal line cuts the function in half.*As you determine the values of "a" and "d", enter them in the input boxes.**(You should not need to zoom out at all. In fact, you can't!)****Click the "Generate New Wave" button as many times as you need until you've mastered this concept!***Once you're correct, you'll know it!*For additional practice in determining the values of the parameters "a" and "d" from viewing the graph of y = a cos(x) + d, go to https://tube.geogebra.org/m/1537251
