Let f be continuous on an interval [a, b] and differentiable on the open interval (a, b). If f'(x) > 0 for every x € (a, b), then we can conclude that (select all that apply): f is strictly decreasing on [a, b]. For every 1,02 € (a, b) f(x₂) - f(x1) f'(x) = X2 X1 - with x₁ < 2, there is an x = (₁, 2) at which f is strictly increasing on (a, b). Of is decreasing on [a, b]. f is a constant function on [a, b]. Of is increasing on (a, b).

ƒ'(x)
X2 - X1
=
f is strictly increasing on (a, b).
Of is decreasing on [a, b].
Of is a constant function on [a, b].
Of is increasing on (a, b).
