(5).5 what is the equation for the graph?

My Driv.. G Civil Rig. biology. Q Databa.. & What D.. E Gaslight.. g Do (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 curve's midline). Suppose f(x) is a function whose graph is a TANGENT curve with the following features 1. Vertical Stretching = 1 2. Period = 3. Phase shift = 0 4. Midline y = 0. Which graph below A-D is the graph of f(x)?| C A B pi/4 -1 C D
