Exercise 10.1
Question # 01: Sketch the graph of the following linear functions:
\((i)\) \(\quad\) \(y=3x-5\)
\((ii)\) \(\quad\) \(y=-2x+8\)
\((iii)\) \(\quad\) \(y=0.5x-1 \)
Question 2: Plot the graph of the following quadratic and cubic functions:
\((i)\) \(\quad\) \( y=x^3+2x^2-5x-6;-3.5\le x \le2.5\)
\((ii)\) \(\quad\) \( y=x^2+x-2\)
\((iii)\) \(\quad\) \( y=x^3+3x^2+2x; -2.5\le x \le 2.5\)
\((iv)\) \(\quad\) \( y=5x^2-2x-3\)
