<h2>Hello!</h2>

The answer is:

C. Cosine is negative in Quadrant III

<h2>Why?</h2>

Let's discard each given option in order to find the correct:

A. Tangent is negative in Quadrant I: It's false, all functions are positive in Quadrant I (0° to 90°).

B. Sine is negative in Quadrant II: It's false, sine is negative in positive in Quadrant II. Sine function is always positive coming from 90° to 180°.

C. Cosine is negative in Quadrant III. It's true, cosine and sine functions are negative in Quadrant III (180° to 270°), meaning that only tangent and cotangent functions will be positive in Quadrant III.

D. Sine is positive in Quadrant IV: It's false, sine is negative in Quadrant IV. Only cosine and secant functions are positive in Quadrant IV (270° to 360°)

Have a nice day!

Can anyone help me with inverse function please? ​
12345 [234]

{h}^{ - 1} oh(x) = x \\  {h}^{ - 1} (4x + m) = x \\ 2k(4x + m) +  \frac{5}{8}  = x \\ 8kx + 2km +  \frac{5}{8}  = x

k and m must satisfy 8k = 1 mean k = ⅛

and 2km+⅝=0 mean m = -5/2
