How do you write the equation of this description: the graph of a parabola has a vertex of (2,3) and vertically stretched by 3

Mademuasel [1]

The equation of parabola is y = 3x²- 12x+ 15.

<u>Step-by-step explanation:</u>

The equation of the parabola is given as y = x².

If it has a vertex then the equation can be written as,

y = a(x-h)² + k

where (h, k ) is the vertex and a is the stretching or compressing factor.

So here the vertex is (2,3) and it is vertically stretched by 3.

So the equation is given as,

y = 3(x-2)² + 3

y = 3(x² -4x+4) + 3

= 3x² - 12x + 12 + 3

y = 3x²- 12x+ 15 is the equation of the parabola.

Pls help I’ll make brainlest and give extra points

Answer:

p>-3 open circle going to the right

$m\leq -4$ closed circle going to the left

n<5 open circle going to the left

$h\geq 2$ closed circle going to the right

1>x open circle going to the left

-1=d just a closed circle

Step-by-step explanation:

Before I answer these here are some good notes

If the inequality sign is < or > then the circle is going to be open

If the inequality sign is $\leq or\geq$ then the circle is going to be closed

If the inequality sign is facing the variable (ex: x>3) then the line is going to be going to the right

If the inequality sign is facing the constant (ex: x<3) then the line is going to be going to the left

p>-3 open circle going to the right

$m\leq -4$ closed circle going to the left

n<5 open circle going to the left

$h\geq 2$ closed circle going to the right

1>x open circle going to the left

-1=d just a closed circle

Hello! is y = 3x - 3 proportional or non-proportional?? please help!

MissTica

A proportional graph is a straight line that goes through the origin while a non-proportional graph is a straight line that doesn't go through the origin.

y = mx + b

the b represents the y-intercept, so -3 is the y-intercept in the equation y = 3x -3

therefore, the line doesn't go through the origin and is a non-proportional equation
