To find the zeros of the function y = 2x^2 + 0.4x – 19.2 using a graphing calculator, follow these steps:
1. Enter the function into the graphing calculator: y = 2x^2 + 0.4x – 19.2
2. Graph the function to visualize the curve.
3. Use the calculator to find the zeros (also known as x-intercepts or roots) of the function.
After performing these steps, the zeros of the function y = 2x^2 + 0.4x – 19.2 are approximately -3.2 and 3. Therefore, the correct answer is:
-3.2 and 3.
