Question

Which of the following has a graph that is wider than the graph of y=4x^2+3 ?y=−4x^2+5y=4x^2+5y=7x^2−4y=2x^2−9

Answer 1

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
