X+1
X2-6x+8?
O all real numbers
O all real numbers except-1
all real numbers except-4 and -2
O all real numbers except 2 and 4

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !

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

do have an equation or graph or
