Question

Choose the letter of the equation for the graph.

Answer 1

The graphed trigonometric function is the one in option a.

Which is the equation of the graph?

The key parts that we can see on the graph are:

• The midline is y = 1.

From this we know that the correct option is either a or b.

• at x = 0, f(x) = 0.

Now we can evaluate options a and b in x = 0 and see which one is equal to zero.

for a:

y = sin(0 - pi/2) + 1 = sin(-pi/2) + 1 = -1 + 1 = 0

for b:

y = cos(0 + pi/2) + 1 = 0 + 1 =  1

Then we can see that option a is the correct option.
