The value of given expression at x=-2 is -7.

Step-by-step explanation:

The given expression is

Substitute x=-2 in the above expression.

Solve the squares and brackets.

Therefore the value of given expression at x=-2 is -7.

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
