Question

what is the equation of the graph shown?

Answer 1

Answer 2

The tangent of an angle is on the unit circle is defined as \[\tan(\theta) = \frac{ y }{ x } = \frac{ \sin(\theta) }{ \cos(\theta) }\]
Where does the tangent function cross the x axis, when y=0. When y is zero, that means sin(angle)=0.
That occurs at angles of 0 and pi radians.
So the regular old Tangent function crosses the X axis at zero and pi degrees.

Answer 4

The one in the picture crosses the x axis, at pi/4, which is shifted that amount.

Answer 5

so is it b?

Answer 6

Graph

tan(A*x + B)

add sliders for A and B and play around and see what changing A and Changing B does to the graph. on that desmos site

Answer 7

B translates
A changes the frequency

Answer 8

That description reminds me of this.
