Step 1

First find the parent function for the given curve, here the curve attains its maximum value at ** x = 0** and maximum value is 0.4, so parent function for this function is cosine function.

Let, the given function is of the form ** f(x) = A cos (B x) + C**.

The Midline of the curve is ** y = 0**, which is located in the middle of graphs maximum and minimum points, so the value of

Step 2

The vertical distance between the midline and the maximum value attains at ** x = 0.4, **So the value of amplitude

** **...
