(5).7 what is the equation of the graph?

My Driv. G Civil Rig. biology.. Databa. & What D... E Gaslight. 9 Down (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 = 3 2. Period = n 3. Phase shift = 0 4. Midline y = 1. Which graph below A-D is the graph of f(x)?| A A B C D
