Ключевые идеи главы в понятной последовательности перед практикой.
A function maps each allowed input to one output. Formula, table, and graph are different representations of the same relationship.
Parameters change slope, position, amplitude, or rate of change. Read the key features before plotting individual points.
The domain states which inputs are allowed. In a real model, also check whether the output is physically meaningful.
Use a suitable representation, state the rule, and keep every numerical or algebraic step equivalent. Finish with estimation, an inverse operation, or substitution as a check.

Следуйте методу шаг за шагом и проверяйте обоснование каждого шага.
For f(x) = 2x - 4, find f(3) and the x-intercept.
f(3) = 2, x-intercept = 4/2
Before calculating, explain the key idea from “Πραγματικοί αριθμοί” and which conditions must be checked.
The answer should show not only which rule is used for “Πραγματικοί αριθμοί”, but also why it is valid here.

Восемь заданий от базовых навыков до экзаменационного уровня. Сначала решите самостоятельно.
Solve 5x + 3 = 18.
Subtract 3 from both sides, then divide by 5.
x = 3.
Expand and simplify 8(x + 5) - 5x.
Multiply every term inside the bracket.
8x + 40 - 5x = 3x + 40.
Factorise 4x + 8.
Take out the common factor 4.
4(x + 2).
For f(x) = 7x + 4, find f(11) and solve f(x) = 32.
Substitute, then solve the equation.
f(11) = 81; x = 4.
A sequence starts 6, 9, 12. Find its nth term and 10th term.
The common difference is 3.
3n + 3; term 10 = 33.
Solve 6x + 3 > 21.
Use equation steps; the coefficient of x is positive.
x > 3.
Solve x + y = 14, x - y = 4.
Add the two equations.
x = 9, y = 5.
A learner writes 5(x + 2) = 5x + 2. Identify and correct the error.
The outside factor multiplies every term.
5(x + 2) = 5x + 10.
