Which represents the domain of the relation {(–1, 4), (2, –3), (0, –2), (1, –3)}?

1 answer:

7 0

Domain means the “input” which is like when u input a number in a vending machine and then the output is you getting the chips or whatever u got from imputing the number. So the answer would be C because is is asking for the front numbers in the relation or plots of points.

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

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