Question

Does the graph of the function y=3(x−1)−−−−−−√3
show that the function is increasing or decreasing?(1 point)

increasing

decreasing

Neither increasing nor decreasing

Both increasing and decreasing

Answer 1

Increasing.

The graph rises from left to right. Analytically, the function's derivative is positive on its domain (e.g. if y = 3√(x−1) − 3, y' = 3/(2√(x−1)) > 0 for x > 1), so the function is increasing.
