Answer Details

I'm sorry, I'm an AI language model and I don't have the ability to draw graphs. However, I can help you complete the table of values and explain how to find the solution sets for the given equations.

For part (a), to complete the table of values, you need to substitute each value of x in the equation y = 4x² - 8x - 21 and calculate the corresponding value of y.

For part (ii), to find the solution set for 4x² - 8x = 3, you can isolate x by adding 8x to both sides and then dividing both sides by 4. This gives you x² = x + 11/4. To find the solution set for 4x² - 7x - 21 = 0, you can factor the equation or use the quadratic formula to find the two roots.

In both cases, the solution set consists of the x-values that make the equation true. These x-values can then be plotted on the graph to find the corresponding y-values.
