Question 1 what is the equation of the following graph? f(x) = cos x f(x) = sin x f(x) = tan x f(x) = cot x

Hello!

The graphs of sine and cosine are waves. Therefore, choice A and B are wrong.

The graph of f(x) = cot(x) is an inverse of f(x) = tan(x), so therefore the graph of f(x) = cot(x) has the lines similar to the graph above, but it's flipped.

So therefore, the graph shown above is choice C, f(x) = tan x.

8.3 and the 3 is repeating

hope this .
