Which of the following statements are true about the graph of f (x) = 1/4 coz ( x + π/3) - 1? Select all that apply.
Jobisdone [24]

Answer:

It has amplitude of \frac{1}{4}.

It is a horizontal shift of the parent function \frac{\pi}{3} units left.

Step-by-step explanation:

We have the function, f(x)=\frac{1}{4}\cos (x+\frac{\pi}{3})-1.

It is clear that the parent function is g(x)=\cos x.

So, we see that,

The amplitude of the function f(x) is \frac{1}{4}, which gives, \cos x => \frac{1}{4}\cos x.

Also, g(x) is translated \frac{\pi}{3} units to the left, which gives, \frac{1}{4}\cos x => \frac{1}{4}\cos (x+\frac{\pi}{3}).

Further, the function is translated 1 unit downward, resulting in f(x)=\frac{1}{4}\cos (x+\frac{\pi}{3})-1.

So, the correct options are,

It has amplitude of \frac{1}{4}.

It is a horizontal shift of the parent function \frac{\pi}{3} units left.

Vinil7 [7]

Answer:

∠MNP is your answer

Step-by-step explanation:

Note the angle and the order it is said. It is ∠ABC, which means the double line side, one curve line angle, and then triple line side.

Now look at the second triangle, the same double line side (NM), one curve line angle (∠N), and triple line side (NP)

Put them together: ∠MNP is your answer
