What is the average rate of change for the function f(x) from x=1 to x=3

if you mean

then it's c. 8, -7/3

but if you mean

then it is

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

yes i do see that. i say this because i am doing my very best in high school so i can get a scholarship and credits.
