Explanation:

From the options given in the question, the use of the subject- verb agreement in all of the sentences A, B and C are wrong. The sentence is in the past perfect tense. Options A, B and C had wrongly used the "perfect" form of the verb as "took, take, taken (without the 'had')". The mistakes in the sentences are as follows-

A. We had took an early flight to Denver before we realized we were a day early for the meeting.

B. We had take an early flight to Denver before we realized we were a day early for the meeting.

C. We taken an early flight to Denver before we realized we were a day early for the meeting.

So, with the use of "had", the verb has to be in the past participle form. Thus, the correct sentence is-

D. We had taken an early flight to Denver before we realized we were a day early for the meeting.

explanation:

. a function is a relation in which each input has only one output. in the relation , y is a function of x, because for each input x (1, 2, 3, or 0), there is only one output y. x is not a function of y, because the input y = 3 has multiple outputs: x = 1 and x = 2.
