Answer:

this is simple once you get the hang of it!! as you see in the chart they gave you, 1=3.15, meaning you graph it (1, 3.15) and so on. all you do is multiply each number (for example, 4) times 3.15 and (4x3.15=6). so 3.15 times all the x-axis numbers and graph it (x, y).. hope this makes sense :)

Y = 3(x-2)^2 + 5

Orlov [11]

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

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