What does it mean if your final exam grade is modeled by the function f(x) = 100 - 3.3x?
A) Your grade increases steadily with every correct answer.
B) Your grade decreases steadily with every incorrect answer.
C) Your grade increases more rapidly with every correct answer.
D) Your grade decreases more rapidly with every incorrect answer.

B) is the correct answer

Step-by-step explanation:

You have a perfect 100 until you get a question wrong which each question is worth 3.3 points. So, if you answered 7 wrong the x would be replaced by the 7 and the grade would decrease steadily.

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
