Explanation
Let us see the graph of each function
• y = 4x² + 3 and y = −4x² + 5
• y = 4x² + 3 and y = 4x² + 5
• y = 4x² + 3 and y = 7x² - 4
• y = 4x² + 3 and y = 2x² - 9
As we can see, the function with a wider graph than the graph of y = 4x² + 3 is the graph of the function y = 2x² - 9.
Answer
y = 2x² - 9
