If the first derivative is positive on a certain interval of a graph, then the function is said to be __________ on that interval.

f(x) = 2x / (x^2 - 1), then what are the HA's

if f"(x) = 0 and f'(x) = 0 at x = a, then f(x) is having local extrema at x =a

If f'(x) = 0 and f"(x) is negative at x = a, f(x) is having __________ at x = a

if f"(x) is positive, f'(x) is __________ and f(x) is ____________

f(x) = x^2 - 3x -4 What are the x intercepts

An interval on a graph where second derivative is negative is referred to as:
