Question

Determine the correct equation of the following graph.

Answer 1

The equation of the given sine graph is gotten as; y = 4 sin [(0.4(x + 2.5)] - 1

How to find the equation of a sine graph?

We know that the  general formula for equation of a sine graph is;

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

where;

A is Amplitude

Period = 2π/B.

Phase Shift = -C/B.

Vertical Shift = D.

From the graph;

A = 4

B = 2π/5π = 2/5

C = -1

D = -5/2

Thus;

y = 4 sin [(0.4(x + 2.5)] - 1
