Answer:

g(x) = 3x² - 7

Step-by-step explanation:

Transformations of Parent Graph: f(x) = a(bx - h)² + k

<em>a</em> is vertical shrink or stretch

<em>b</em> is horizontal shrink or stretch

(<em>h, k</em>) is the vertex

<em>k</em> is vertical movement

We are given that <em>a</em> = 3, <em>k </em>= -7, so simply plug it into the formula:

g(x) = 3(x - 0)² - 7

g(x) = 3x² - 7

Answer:

g(x) = 3x^2-7

Step-by-step explanation:

f(x) = x^2 is vertically stretched by a factor of 3 and shifted down 7 to form g(x)

we have

g(x) = 3x^2-7

3 = vertical stretch factor

-7 = translation downwards 7 units.

Minchanka [31]
2 3/4 acres is the same as 11/4 acres
To find how much of the land is beans, find how much is already taken up, and the rest is beans.
Farmland-Corn-Potatoes-Wheat=Beans
1-(1/4)-(1/12)-(5/8)=1/24

Corn: (1/4)x(11/4)=11/16 acres
Potatoes: (1/12)x(11/4)=11/48 acres
Wheat: (5/8)x(11/4)=55/32 acres or 1 23/32 acres
<span>Beans: (1/24)x(11/4)=11/96 acres

How do i factorise this equation <br> 25x²-p²
kondaur [170]

You can write it in the form a^2 - b^2 where a = 5x and b = p

(5x)^2 - p^2

And then use the Difference of Squares a^2 - b^2 = (a + b)(a - b)

Answer is (5x + p)(5x - p)
