Draw the graph for the equation y = 2x2 − 5x − 3 for x from -2 to +6 using a scale of 2cm to 1 unit on the x-axis and 2cm to 5 units on the y-axis.

Here are the solutions to the questions.

Question 51:

• Given: The equation $y = 2x^2 - 5x - 3$.
• Task: Draw the graph for $x$ from $-2$ to $+6$ using a scale of 2cm to 1 unit on the x-axis and 2cm to 5 units on the y-axis.

Step 1: Create a table of values for $y = 2x^2 - 5x - 3$.

$x$	$2x^2$	$-5x$	$-3$	$y$
-2	8
