Mom just got a new department store credit
card in the mail. What is the probability that
the last digit is an odd number?

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

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
