The value of ad is:

a. 27

b. 28

c. 26

27

Step-by-step explanation:

Angles ABD and DBC are congruent (they are marked as such in the diagram).  That means that the sides across from these angles are also congruent:  AD = CD.  Therefore, we set them equal to each other:

3x = 2x + 9 and

x = 9.

That means that 3x --> 3(9) = 27

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
