3.5-bo'lim : Grafikalash funktsiyalari
1-13-masalalar uchun funksiya grafigida kamida 4 ta tartiblangan juft nuqtadan iborat jadval tuzing va funksiya grafigini chizish uchun jadvaldagi tartiblangan juftlardan foydalaning.
- \(f\left( x \right) = 6x - 1\)
- \(f\left( x \right) = 3 - 5x\)
- \(f\left( x \right) = 2{x^2}\)
- \(f\left( x \right) = {x^2} + 7\)
- \(f\left( x \right) = \sqrt {x + 3} \)
- \(f\left( x \right) = \sqrt {6 - x} \)
- \(\displaystyle f\left( x \right) = \frac{1}{x}\) , faqat ijobiy \(x\) dan foydalaning
- \(\displaystyle f\left( x \right) = \frac{1}{x}\) , faqat salbiy \(x\) dan foydalaning
- \(f\left( x \right) = \left\{ {\begin{array}{*{20}{l}}3&{{\rm{if }}x \ge 0}\\{4 - x}&{{\rm{if }}x < 0}\end{array}} \right.\)
- \(f\left( x \right) = \left\{ {\begin{array}{*{20}{l}}{4x}&{{\rm{if }}x \le - 2}\\{3 - 2x}&{{\rm{if }}x > - 2}\end{array}} \right.\)
- \(f\left( x \right) = \left\{ {\begin{array}{*{20}{l}}{2 - {x^2}}&{{\rm{if }}x < 1}\\{{{\left( {x - 2} \right)}^2}}&{{\rm{if }}x \ge 1}\end{array}} \right.\)
- \(f\left( x \right) = \left\{ {\begin{array}{*{20}{l}}{{x^2}}&{{\rm{if }}x > 3}\\4&{{\rm{if }} - 2 \le x \le 3}\\{1 - x}&{{\rm{if }}x < - 2}\end{array}} \right.\)
- \(f\left( x \right) = \left\{ {\begin{array}{*{20}{l}}{1 - x}&{{\rm{if }}x \ge 1}\\{{x^2} - 1}&{{\rm{if }} - 1 < x < 1}\\{ - 1 - x}&{{\rm{if }}x \le - 1}\end{array}} \right.\)
