Given f ( x ) = x + 4 and g ( x ) = √ x + 5 , determine the following. Write each answer using interval notation. Domain of f ( g ( x ) ) : Domain of g ( f ( x ) ) :
Answers
Answer:
In Functions and Function Notation, we were introduced to the concepts of domain and range. In this section, we will practice determining domains and ranges for specific functions. Keep in mind that, in determining domains and ranges, we need to consider what is physically possible or meaningful in real-world examples, such as tickets sales and year in the horror movie example above. We also need to consider what is mathematically permitted. For example, we cannot include any input value that leads us to take an even root of a negative number if the domain and range consist of real numbers. Or in a function expressed as a formula, we cannot include any input value in the domain that would lead us to divide by 0.

Answer:
The answers are f(g(x))=x−7 and g(f(x))=√x2−7. Explanation: This is a composition of functions. f(x)=x2−4. g(x)=√x−3.

What is the value of x in the equation 3x-y = 30, when y = 15?
Answers

f
[tex]x=200[/tex]
Explanation:
Okay so we can start by substituting in [tex]y[/tex] as we know what it is already:
[tex](\frac{1}{5} )x-(\frac{2}{3} )(15)=30[/tex]
Now at this stage we could use a calculator to figure out what [tex]\frac{2}{3}[/tex] of [tex]15[/tex] are though a bit of mental math is as easy:
[tex](\frac{15}{3} )[/tex] · [tex]2=[/tex] [tex]5[/tex] · [tex]2[/tex]
okay so now we have:
[tex](\frac{1}{5} )x-10=30[/tex] add 10 to both sides to get rid of the [tex]-10[/tex]
[tex](\frac{1}{5})x=40[/tex] let's get rid of that fraction by multiplying by [tex]5[/tex]
and there's the solution for x
We can check we got this right by substituting it back into the original equation with the known y:
[tex](\frac{1}{5} )(200)-(\frac{2}{3})(15)=30[/tex]
now, and we already know what out of is so :
that means
which is ✓
Therefore we know our solution is right.

Find g(x), where g(x) is the reflection across the y-axis of f(x)= –9|x–10|+1.
Answers
Answer:
To reflect a graph, f(x) over the x-axis, you take -f(x).
So if f(x)=x^2, then -f(x) is -x^2.
Then g(x)=-x^2 is the reflection of your function f(x) over the x-axis.

Answers
The equation in point-slope form to represent the time y it took to download x songs is; (y - 35) = 7(x - 5)
Since it took 35 seconds for 5 songs to downloadand it took 42 seconds for 6 songs to downloadIn essence, we can represent the information as;

g(n) = 2n + 3
h(n)=n-1
Find (g•h)(n)
Answers
Answer:
Step-by-step explanation:
g(n) = 2n + 3
h(n) = n − 1
(g * h)(n) = g(h(n))
= g(n − 1)
= 2(n − 1) + 3
= 2n − 2 + 3
= 2n + 1

Length of rectangle is 4 m less than 3 times its breadth. If the perimeter of rectangle is 32 m. Find its length and breadth B=12
Answers
Answer:
Length = 11m and the Breath = 4m
Step-by-step explanation:
L = 3B - 4
p = 32m
2( L + B ) = 32
L + B = 32/2
L + B = 16
(3B - 4) + B = 16
3B - 4 + B = 16
4B - 4 = 16
4B = 16 + 4
4B = 20
B = 20/4 = 5m
B = 5m
L = 3B - 4
L = 3(5) - 4
L = 15 - 4
L = 11m
