Question

Consider the function graphed at right. The function has a:Of:At x=The function is increasing on the intervals :The function is decreasing on the intervals :

Answer 1

In this problem

we have a quadratic equation (vertical parabola) open downward

so

the function has a maximum of vertex at (1,1)

the function is increasing on the interval ------> (-infinite, 1)

the function is decreasing on the interval -----> (1, infinite)
