Final answer:
To calculate the values of f(1)+ f(-1)+ f(0) for the function f(x)=5x² -4x 5, we substitute the given values into the function. Adding these values gives us the result: f(1) + f(-1) + f(0) = 25.
Step-by-step explanation:
To calculate the values of f(1)+ f(-1)+ f(0) for the function f(x)=5x² -4x 5, we substitute the given values into the function.
For f(1), we have f(1) = 5(1)² - 4(1) + 5 = 5 - 4 + 5 = 6.
For f(-1), we have f(-1) = 5(-1)² - 4(-1) + 5 = 5 - (-4) + 5 = 14.
Finally, for f(0), we have f(0) = 5(0)² - 4(0) + 5 = 0 - 0 + 5 = 5.
Adding these values gives us the result: f(1) + f(-1) + f(0) = 6 + 14 + 5 = 25.
