Which answer classifies the function using finite differences? - a. The function is linear with a constant first difference of –3. b. The function is linear with a constant first difference of 3. c. The function is quadratic with a constant second difference of –3. D. The function is quadratic with a constant second difference of 3.

the first option is the answer.

ca = ec

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.

step-by-step explanation:

consider the parallelogram shown in the attached image.

in the parallelogram hijk, the length of hk is given as,

from the properties of parallelogram we know that the opposite sides of a parallelogram are parallel to each other and are equal in measure.

therefore, the length of the side ij must be equal to the length of the side hk and that is .

hence, the expression for the length of ij confirms that hijk is a parallelogram.
