IB MATH AA HL, Paper 1, May, 2021, TZ1, Solved Past Paper
Master the 2021 IB May for Paper 1 Mathematics AA HL with examiner tailored solutions and comments for TZ1
Question 1 [Explained]
Consider the function ( y = f (x)). We are focusing on how this function behaves between the values of (x) ranging from -4 to 6. We want to understand the shape and the journey of this function's graph within this interval.
This function's graph will tell us how ( y), the output, changes as (x), the input, varies within the given range. It's a way of visualizing the function's behavior and seeing at a glance where it increases, decreases, or has any special features like peaks or troughs.
Question 1 [a] [Explanation]
Identify the numerical value of the mathematical expression provided. This involves calculating the result based on the given numbers and variables.

Question 1 [a] [i] [Explanation]
Consider a function represented by ( f ). Our objective is to compute the result when the argument of the function is 2.
Question 1 [a] [ii] [Explanation]
Consider a function ( f ) and find what result we get when we apply this function to the number 2 and then apply the function again to the result of the first application.
In mathematical terms, this is asking for the evaluation of the composition of the function ( f ) with itself at the point 2, denoted as
Question 1 [b] [Explanation]
Consider the function
Could you plot this function over the specified range? It's essentially a transformation of the function ( f (x)), scaled down by half and shifted upward by one unit on the graph.

Question 2 [Explained]
Let's explore an arithmetic sequence where the eighth term is given as 8. Could you figure out the initial value of the sequence, often referred to as (u1), and determine the consistent step by step increase between the terms, known as the common difference (d)?
Here's how you could explain this question simply: We're talking about a list of numbers where each one is a certain fixed amount more than the one before it. The eighth number in this list is 8. What's the very first number, and what is that fixed amount that each number goes up by?
