Q:

PLEASE HELP ASAP WILL GIVE 48 POINTS AND MARK BRAINLESS#1 Given the relation y = 3x2 + 1, if the input is 4, what is the output?134849145 # 2 Consider the following scenario describing Mr. Smith's math students: A list pairs math grades with student heights.Does this scenario represent a function?Yes, because students who have the same math grade can be different heightsYes, because students who are the same height can have different math gradesNo, because students who have the same math grade can be different heightsNo, because students who are the same height can have different math grades#3 Which of the following best defines an output?An output is the value that determines another based on the relation or the function rule, usually the x-values in a set of ordered pairs or on a table or graph.An output is the result of a relation or the function rule, usually the y-values in a set of ordered pairs or on a table or graph.An output is a special type of relation for which there is a rule that pairs each input with exactly one output.An output is a set of ordered pairs in which no y-value repeats.

Accepted Solution

A:
1. Input and output is simple. The equation is Y=3x^2+1, and the input is 4 (x), so the output (y), is what we need to find. Using the equation, follow out the rules of PEMDAS. 4^2=16*3=58+1=49.
Answer is 49

2. This is an irrational Function. The most logical answer is C, but it can also be D

3.  Output is always Y. Seems your answer is the second choice. 
4: Answer is A, {-3, -1, 3, 4}
