Question

Which points are on the graph y tan x? Select two of the following that apply,

Answer 1

Answer:

Option 1 and Option 4.

Step-by-step explanation:

The given graph is y = tanx

Now we will check the points given in the option.

For (4π/3, √3)

y = tan(4π/3) = tan(π+π/3) = tan(π/3)        [tan(π+∅) = tan∅]

y = √3

right option.

For (π/4,-1)

y = tan(π/4)=1

Therefore incorrect option.

For (π/6, -√3/3)

y = tan(π/6) = 1/√3 = √3/3

So incorrect option.

For (π/3, √3)

y = tan π/3 = √3

Correct option.

For (1, -π/4)

y = tan(1) = value in radians will be positive

So  incorrect option.
