Find the domain and range of the function. f(x) = 9x² + 3 domain range

Mathematics
1 answer:
zloy xaker [14]2 years ago
5 0

Answer:

Domain: all real numbers, or (-oo, oo)

Range: (3, oo).

Step-by-step explanation:

The domain is the set of x-values that work when plugged into a function. Here, all values when plugged in produce a real answer, so the answer is all real numbers, or (-oo, oo).

The range is the result of the domain, or the y-values. Since the x^2 will only produce positive numbers, the lowest y-value we can get is 3, and the highest y-value we can get is infinity. So, the answer is (3, oo).

Brainliest, please :)

5/6 n=10 show me how to solve it please
Mila [183]

Hey there! :)

Answer:

n = 12.

Step-by-step explanation:

Given:

5/6n = 10

Solve by isolating the variable. Divide both sides by 5/6. (Multiply by the reciprocal)

5/6n · 6/5 = 10 · 6/5

n = 10 · 6/5

n = 12.

Solve each equation for the indicated variable <br><br> g = c + x solve for x
Elis [28]

Answer:

<h2>x = g - c</h2>

Step-by-step explanation:

g = c + x           |<em>subtract c from both sides</em>

g - c = c - c + x

g - c = x → x = g - c

Given the system of equations, what is the x-coordinate of the solution?
Nimfa-mama [501]
Answer: Choice C) -11

-----------------------------------

Explanation:

The first equation given is y = 3 - 1/2x
In other words, y is the same as 3 - 1/2x. 
We can replace y in the second equation with 3 - 1/2x
This is known as substitution (think of a substitute teacher who is a temporary replacement for your teacher)

Doing this leads to...
3x+4y = 1
3x+4*y = 1
3x+4*( y ) = 1
3x+4*( 3 - 1/2x ) = 1 <<--- y has been replaced with 3-1/2x
3x+4*(3) +4*(-1/2x) = 1
3x+12-2x = 1
3x-2x+12 = 1
x+12 = 1
x+12-12 = 1-12 <<-- subtracting 12 from both sides
x = -11
Which is why the answer is choice C) -11
