Question

Find an equation that fits the graph below; choose one of the following forms

Answer 1

Step 1:

Write the two equations

$y\text{ = }A\sin \lbrack B(x\text{ - C)\rbrack + D and y = Asin\lbrack{}B(x-C)\rbrack + D}$

Step 2:

The amplitude of graph A = 2

The midline of the graph is D = 0

The graph is a sin graph.

y = 2sin[B(x - C)] + 0

y = 2sin[B(x - C)]

Final answer

y = 2sin[B(x - C)] + D
