The vertices of trapezoid ABCD are A(3,-2), B(7, - 2), C(8, – 7), and D(1, -7). Graph ABCD and A'B'C'D', its image after a reflection across the x-axis.
Which graph shows ABCD and A'B'C'D'?

answer: about 22.67

step-by-step explanation:

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

b, i believe, but not sure.
