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

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

Hence the x-intercept is (43/9, 0)

The y-intercept is the point where x = 0

$y=3(x-2)^2 + 5\\y=3(-2)^2 + 5\\y=12+5\\y=17$

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

-12,60,-300,1500 what are the next two numbers on the pattern

Rina8888 [55]

Answer:

The next two numbers are -7500 and 37500

Step-by-step explanation:

To find the pattern, divide any number by the previous.

-300/60 = -5.

Meaning they are being multiplied by -5, so we can just multiply this to the last number.

1500 * -5 = -7500,

-7500 * -5 = 37500.

Use the figure to find the measurements of the numbered angles

sineoko [7]

Angle 1 would 107° since a and b are parallel. Angle 2 would be 180° - 107° = 73°.
