Answer:
y = tan(x -π) -1
Step-by-step explanation:
It looks like a straight tangent function shifted down one unit. Since the tangent function has a period of π, ...
tan(x -π) = tan(x)
so you're only looking for the function that has a translation downward of 1 unit. Of course that translation is accomplished by adding -1 to the original function.
The appearance of the graph is of ...
y = tan(x) -1
The choice that is equivalent to this is ...
y = tan(x -π) -1
Answer:
y = tan (x-pi)-1
Step-by-step explanation:
The function in the graph is a periodic function with intervals of pi and having discontinuities at regular intervals.
Hence this must be a transformation of the original trignometric funciton
tan x. y intercept is at -1 which shows that there is a vertical shift of 1 unit down.
Hence the funciton is y = tanx-1
But tan x is not given in any of the options.
Let us check which is equivalent to tan x-1
We find that tan(x-pi) = -tan (pi-x) = -(-tanx) = tanx
Hence the option 3 is the right answer
