#### Answer:

Have a look if it makes sense:

#### Explanation:

Your sinusoidal function oscillates between

The period of your function is 20 seconds (after which it repeats itself); for this reason the

Your function seems a cosine but starting from the negative and shifted up of 10 feet.

I would write it as:

height:

Graphically:

graph{10-7cos((pi/10)*x) [-52, 52.04, -26, 26.03]}

#### Answer:

y= 7sin

#### Explanation:

The equation can also be written in terms of sine function. From the graph the horizontal shift can be noted to be 5 units, amplitude being 7, vertical shift being 10, the sinusoidal function would be y= 7 sin
