Question

C'mon people! For the function g(x) = 2x2 – 19, what is the difference quotient?

A. 2h; h ≠ 0

B. 2x + 2h; h ≠ 0

C. 4x + 2h; h ≠ 0

D. 4x + 2h – 19; h ≠ 0

Answer 1

Explanation:

A 2-column table with 6 rows. Column 1 is labeled x with entries 1.99, 1.999, 1.9999, 2.0001, 2.001, 2.01. Column 2 is labeled f (x) with entries 0.505, negative 0.827, 0.306, negative 0.306, 0.827, negative 0.506.

Find Limit of f (x) as x approaches 2 f(x), if it exists.
