Answer: B

Step-by-step explanation:

The slope-intercept is usually written as y = mx + b form, where m is the slope, and b is the y-intercept. The y-intercept is the y value when x is equal to 0.

We can first eliminate C, because the y-intercept of the graph is 1.

To solve for slope, which is the m, choose two points, (-1, 5) and (1, -3).

Slope = (y2 - y1) / (x2 - x1)

= (-3 - 5) / (1 - (-1))

= (-3 - 5) / (1 + 1)

= -8/2

= -4

Plug in the slope and y-intercept, we get y = -4x + 1

The y-intercept coordinate is at the point (0, 17)

<h3>Properties of functions</h3>

Given the following function expressed as:

$y = 3(x-2)^2 + 5$

The vertex of the function (h, k) is (2, 5) while the axis of symmetry is at x = 2
Domain are the input values for which the function exist. According to the function, the domain and range exists on all real values

The x-intercept is the point where y = 0

$3(x-2)^2 + 5=0\\3(x-2)^2 = -5\\(x-2)^2 = -5/3\\x - 2 = 25/9\\x = 25/9 + 2\\x = \frac{43}{9}$
