Gerald graphs the function f(x) = (x – 3)2 – 1. which statements are true about the graph? check all that apply. 1-the domain is {x| x ≥ 3}. 2-the range is {y| y ≥ –1}. 3-the function decreases over the interval (–∞, 3). 4-the function increases over the interval (–1, ∞). 5-the axis of symmetry is x = –1. 6-the vertex is (3, –1).

Options 2,3,6 are right

Step-by-step explanation:

Given is a quadratic function as

This is a parabola in vertex form

Vertex = (3,-1)

Open up since leading term is positive

symmetrical about x =3

Range is y≥-1

The function decreases for x<3

Increases for x >3

Hence the correct options are

Option 2, 3, 6

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a
