Find a function of the form y=asin(kx)+c or y=acos(kx)+c whose graph matches the function shown. ( in the picture)

The required function is .

Step-by-step explanation:

From the given graph it is clear that the value of function is not extreme at x=0, so the required function is a sine function.

The general form of a sine function is

                ..... (1)

where, A is amplitude, is period and C is midline.

From the given graph it is clear that the maximum value of the function is -2 and minimum value of the function is -4.

The function complete a cycle in 14 units, so period of the function is 14.

Substitute A=1, and C=-3 in equation (1).

Therefore the required function is .

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3

use this formula:

p(a\b) = p(a and b)/p(b).
