You survey 284 students about whether they use a laptop or tablet. One hundred twelve of the students use a laptop, with 49 of them also using a tablet.
Ninety-seven of the students do not use a laptop or a tablet. Organize the results in a two-way table. Include the marginal frequencies.

i believe the answer is 68cm

step-by-step explanation:

i just took 34 x 2 because the space between v and y is the same as y to k.

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
