The three terms a, 1, b are in an arithmetic sequence. The three terms , 1, a, b are in a geometric sequence. Find the value of a and of b given that a # b

x/3-10=8

x/3=18

x=48

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
