Your answer will be D

As y = -(x+2)(x-1)

Thus the external negative sign will flip the positive 2 into a negative & negative 1 into a positive; Resulting, y=(x-2)(x+1)

We can fairly easily solve this by looking at the direction the graph is pointing, and the x-intercepts.

We see that the graph is pointing down, so we can immediately rule out A and C because they both do not have a -

When we look at the x-intercepts we see they are -2 and 1

Only D when -2 or 1 are plugged in will return an answer of 0

Answer:

Given equation: $y=(x+1)^2-2$

The function is a quadratic function in vertex form: $y=a(x-h)^2+k$

Translations

For $a > 0$

$f(x+a) \implies f(x) \: \textsf{translated}\:a\:\textsf{units left}$

$f(x-a) \implies f(x) \: \textsf{translated}\:a\:\textsf{units right}$

$f(x)+a \implies f(x) \: \textsf{translated}\:a\:\textsf{units up}$

$f(x)-a \implies f(x) \: \textsf{translated}\:a\:\textsf{units down}$

Parent function: $f(x)=x^2$

Translations

Translated 1 unit left: $f(x+1)=(x+1)^2$

Then translated 2 units down: $f(x)-2=(x+1)^2-2$

Therefore, translate the parent function by 1 unit left and 2 units down to produce the given equation.

Answer

Given: Sorry the images are at the bottom.

To find:

Part A: Write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x).

Part B: Which function has a greater y-intercept? Justify your answer.

Solution:

On inspection of values of x and f(x) it is clear that f(x) is a linear function

i.e.

1)Slope of f(x) and y-intercept of f(x):

Convert the function in slope intercept form and calculate the slope.

Slope intercept form:

Here,

Slope of f(x)=1,

y-intercept of f(x)=(0,0)

2) Slope and y-intercept of g(x):

Slope of g(x)=7

Y-INTERCEPT of g(x) =(0,2)

Part A:

Slope of f(x) is 1 and slope of g(x) is 7.

Part B:

g(x) has a greater y-intercept.

Hope it helps you.

Rearrange the formulae to make x the subject: ay/x - dx= wx Thanks in advance

Lina20 [59]

Answer:

$\frac{ay}{x} - dx = wx$

multiply x through out:

$ay - {dx}^{2} = w {x}^{2} \\ {wx}^{2} + {dx}^{2} = ay$

factorise out x²:

${x}^{2} (w + d) = ay \\ {x}^{2} = \frac{ay}{w + d}$

take square root on both sides:

$\sqrt{ {x}^{2} } = \sqrt{ \frac{ay}{w + d} } \\ \\ x = \sqrt{ \frac{ay}{w + d} }$
