Answer:

3

Step-by-step explanation:

y = 4x - 6

x = 4y - 6  

x + 6 = 4y

y = x + 6 / 4

g -1 (x) = x/4 +6/4

= answer 3

Given:

g(x)=4x-6

To find:

The function g^{-1}(x).

Solution:

we have,

g(x)=4x-6

Put g(x)=y.

y=4x-6

Interchange x and y.

x=4y-6

Isolate y.

x+6=4y

\dfrac{x+6}{4}=y

y=\dfrac{x+6}{4}

Substitute y=g^{-1}(x).

g^{-1}(x)=\dfrac{x+6}{4}

g^{-1}(x)=\dfrac{x}{4}+\dfrac{6}{4}

g^{-1}(x)=\dfrac{x}{4}+\dfrac{3}{2}

Therefore, the correct option is (3).

Carmen wants to know the favorite lunch menu among 6th grade students. Which types of survey below would give Carmen valid resul
AlladinOne [14]

Answer:

D

Step-by-step explanation:

Randomly surveying sixth grade students would give the most accurate result, as randomly surveying students in middle school wouldn't just be limited to 6th graders, sixth grade teachers would not be relevant as Carmen wants to know the favorite lunch menu amount 6th grade students, sixth grade boys would only include a certain gender, which is not the focus of the study. Therefore, D would be the best choice

Tell whether the ratios are proportions: 11/12, 33/36
REY [17]

Yes, they're proportional.

If you simplify 33/36 (divide the numerator and denominator by 3) you get 11/12, so it's proportional (equal) to 11/12.

Determine the function which corresponds to the given graph. (3 points) a natural logarithmic function crossing the x axis at ne
quester [9]

Answer:

y =log_e(x+3)

Step-by-step explanation:

It is given that the graph corresponds to a natural logarithmic function.

That means, the function y has a natural log (Log with base e) of some terms of x.

It is given that asymptote of given curve is at x= -3. i.e. when we put value

x= -3, the function will have a value y \rightarrow \infty.

We know that natural log of 0 is not defined.

So, we can say the following:

log_e(x+a) is not defined at x= -3

\Rightarrow x+a =0\\\Rightarrow x = -a

i.e. x =-a is the point where y \rightarrow \infty

a = 3

Hence, the function becomes:

y =log_e(x+3)

Also, given that the graph crosses x axis at x = -2

When we put x = -2 in the function:

y =log_e(-2+3)  = log_e(1) = 0

And y axis at 1.

Put x = 0, we should get y = 1

y =log_e(0+3)  = log_e(3) \approx 1

So, the function is: y =log_e(x+3)

Let u = in x and v = in y. Write in(x3y2) in terms of u and v
sleet_krkn [62]

Answer:

Step-by-step explanation:

you mean u=ln x,v=ln y

ln(x^3y^2)=lnx^3+ln y^2

=3 ln x+2 ln y

=3u+2v
