Consider the graph of the function f(x) = 2(x + 3)2 + 2. over which interval is the graph decreasing? (–∞, –3) (–∞, 2) (–3, ∞) (2, ∞)

(–∞, –3)

Step-by-step explanation:

The function is a quadratic function of order 2 and positive coefficient.

This is in the form of the function , but it is displaced 3 units to the left of the x axis and two units up in the y axis. type of functions are decreasing from -∞ to its vertex and then they are increasing from the vertex to infinity.

Observe in the attached graph that this function has its vertex in the point (-3, 2) and is decreasing from -∞ to x = -3. Then it is increasing until ∞. Therefore the correct option is:

(-∞, -3)

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

you,

mrb

i have no idea just need points sorry
