Answer:

<em>y </em>= ± \sqrt{\frac{(a-x)}{2b}}

Step-by-step explanation:

x = a - 2by²

<em>Take -2by² to the left side.</em>

x + 2by² = a

<em>Take x to the left side.</em>

2by² = a - x

<em>Divide both sides by 2b.</em>

y² = \frac{(a-x)}{2b}

<em>Now remove the y square.</em>

<em>y </em>= ± \sqrt{\frac{(a-x)}{2b}}

Answer:

See below

Step-by-step explanation:

x=a-2by^2   Subtract 'a' from both sides

x -a = - 2 by^2     divide both sides by - 2b

(a-x)/2b = y^2    sqrt both sides

y =  +- sqrt ( (a-x)/2b))

F(x)=4^x and g(x)=4^x+2
dsp73

Given:

The two functions are:

f(x)=4^x

g(x)=4^x+2

To find:

The type of transformation from f(x) to g(x) in the problem above and including its distance moved.

Solution:

The transformation is defined as

g(x)=f(x+a)+b                .... (i)

Where, a is horizontal shift and b is vertical shift.  

  • If a>0, then the graph shifts a units left.
  • If a<0, then the graph shifts a units right.
  • If b>0, then the graph shifts b units up.
  • If b<0, then the graph shifts b units down.

We have,

f(x)=4^x

g(x)=4^x+2

The function g(x) can be written as

g(x)=f(x)+2            ...(ii)

On comparing (i) and (ii), we get

a=0,b=2

Therefore, the type of transformation is translation and the graph of f(x) shifts 2 units up to get the graph of g(x).

Tempestt graphs a function that has a maximum located at (-4, 2). Which could be her graph?
son4ous [18]

Answer:

Here's what I get  

Step-by-step explanation:

Assume the function is a parabola.

The function has a maximum, so the parabola opens downward.

The maximum is at (-4,2), so the maximum is in the second quadrant.

The figure may look like the diagram below.
