Which sequences of transformations will map circle<br><br> M onto circle N?
sergiy2304 [10]

Answer:

1: Reflect M across the x-axis

2: Dilate about the center by 3/2

Step-by-step explanation:

Given

See attachment for M and N

Required

Which maps M to N

The coordinates of the radius of the circles are:

M = (5,5)

N = (5,-5)

And the radius of circles are:

r_M=2

r_N=3

The first transformation from M to M' is:

- Reflect across the x-axis

The rule is:

(x,y) \to (x,-y)

M(5,5) \to M'(5,-5)

<em>At this point, M' and N now have the same center but different radius.</em>

The second transformation from M' to N is:

- Dilate about the center by dividing the radius of N by the radius of M

i.e.

k =\frac{r_N}{r_M}

k =\frac{3}{2}

<em>At this point, M has been completely mapped to N.</em>

For the function f(x)=|x−7|−4, evaluate f(x+1).
GarryVolchara [31]

Answer:

\displaystyle{f(x+1)=|x-6|-4}

Step-by-step explanation:

To evaluate \displaystyle{f(x+1)}, substitute \displaystyle{x} to \displaystyle{x+1} so we should have:

\displaystyle{f(x+1) = |x+1-7|-4}

Evaluate the expression and finally, we have:

\displaystyle{f(x+1)=|x-6|-4}

F(x)=2x and g(x)=square root of x what is the domain of f(g(x))?
Dmitriy789 [7]

Answer:

x\ge 0

Step-by-step explanation:

The given functions are:

f(x)=2x


and


g(x)=\sqrt{x}


Now,

f(g(x))=f(\sqrt{x} )


f(g(x))=2\sqrt{x}

The domain refers to values of x for which f(g(x))=2\sqrt{x} is defined.


The  expression under the radical sign must not be negative.

The domain is

x\ge 0
