what is the equation of the graph?

(2 points) TANGENT curves on the plane have four basic features: vertical stretching, period, phase shift (sometimes called horizontal shift), and vertical shift (sometimes represented by the equation of the sinusoid's midline). Suppose f(x) is a function whose graph is a TANGENT curve with the following features 1. Vertical Stretching = 2. Period = 3. Phase shift = 0 4. Midline y = 0 Which graph below A-D is the graph of f(x) ? B
