Final answer:
The difference quotient for the function f(x) = 5x² - x/6 is (5h² - h)/6h
Step-by-step explanation:
The difference quotient for the given function, f(x) = 5x² - x/6, can be found by subtracting the value of the function at x+h from the value of the function at x, and then dividing the result by h. This can be expressed as:
(f(x+h) - f(x))/h
To calculate this, we need to substitute x+h and x into the function and simplify:
f(x+h) = 5(x+h)² - (x+h)/6
f(x) = 5x² - x/6
Now, we can subtract f(x) from f(x+h) and divide the result by h:
((5(x+h)² - (x+h)/6) - (5x² - x/6))/h
This simplifies to:
(5h² - h)/6h
