What is amplitude and period of f(t)= -tan 0.4 t

No Amplitude

Period =  

Step-by-step explanation:

We can say a general function for Tan function as:

This function given is:

f(t) = - Tan (0.4t)

First of all, there is no amplitude for a tan function because it goes on and on in both y-directions. THere is no max or min value, so there is no Amplitude.

As for period, the normal period (distance between 2 vertical asymptotes of a tan function) is  (180 degrees).

Since this function has a b value, the period would be:

So,

b = 0.4, so we have:

THis is the period , in terms of pi.

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
