Let f(x)=e* and g(x)= X+6. What are the domain and range of (gºf)(x)?

Answers

Answer:

Domain: Set of All Real Numbers. (-∞, ∞)

Range: (0, ∞)

Step-by-step explanation:

f(x)=e^(x)\ng(x)=x+6

We need to evaluate (gof)(x). (gof)(x) means the composition of function g(x) and f(x). In order to find (gof)(x) replace every occurrence of x in g(x) with the expression of f(x) as shown below:

(gof)(x)=g(f(x))\n\n =g(e^(x))\n\n =e^(x)+6

We have to find the domain and range of this composite function.

Domain:

The expression e^(x)+6 is defined for all Real Numbers. It never gets undefined for any value of x. Hence the Domain is set of All Real Numbers.

Range:

The range of the parent exponential function e^(x) is from 0 to positive infinity. The expression e^(x)+6 can be related to e^(x) as a vertical shifted function by 6 units upward. As a result the range will also be shifted up. So the range of the composite function will be from 6 to positive infinity. In interval notation this would be expressed as: (0, ∞)

6 divded by 2/3 = what

Answers

you keep the first number the way it is, and multiply by the reciprocal of the second number so:

6/1 * 3/2

6*3=18
1*2=2

So then you have 18/2 which is 9

Answer: 9

Explantion:

Divide: 6 : 2/

= 6/

= 6 · 3/

= 18/

= 2 · 9/

2 · 1

= 9

Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 2/

) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the next intermediate step, , cancel by a common factor of 2 gives 9/

Option D:

Difference between g(x) and f(x) is 44.

Solution:

Let us first write the function of f(x).

Take any two points on the line (0, -1) and (-2, 0).

Here, x_1=0, y_1=-1, x_2=-2, y_2=0

Equation of a line:

$(y-y_1)/(x-x_1) =(y_2-y_1)/(x_2-x_1)

$(y-(-1))/(x-0) =(0-(-1))/(-2-0)

$(y+1)/(x) =(1)/(-2)

Do cross multiplication.

-2(y + 1) = x

-2y - 2 = x

Add 2 on both sides.

-2y = x + 2

Divide by -2 on both sides.

$y=-(1)/(2)x-1

y = -0.5x - 1

f(x) = -0.5x - 1

At x = 20,

f(20) = -0.5(20) - 1 = -11

g(x) = 1.5x + 3

g(20) = 1.5(20) + 3 = 33

Difference between g(x) and f(x)

            = g(20) - f(20)

            = 33 - (-11)

            = 33 + 11

            = 44

Difference between g(x) and f(x) is 44.

Option D is the correct answer.
