What is the domain of f(x) = 2^x?
hammer [34]

The given function has no undefined points nor domain constraint. Thus, the domain is: -\infty \: < x < \infty.

<h3>Domain and Range</h3>

The domain of a function is the set of input values for which the function is real and defined. In the other words, when you define the domain, you are indicating for which values x the function is real and defined. An example, there is a restriction for the domain of fractions. The variable x in the denominator should be different of zero.

While the domain is related to the values ​​of x, the range is related to the possible values ​​of y that the function can have.

In this question, the function 2^x has no undefined points nor domain constraint. Therefore, the domain is: -\infty \: < x < \infty

Hitman42 [59]

Answer:

\huge\boxed{\sf 9x^2+12x+4 \ units^2}

Step-by-step explanation:

Given that,

Length of cube = l = 3x + 2 units

<h3><u>Base Area:</u></h3>

= l \times l\\\\= (3x+2)(3x+2)\\\\= 3x(3x+2)+2(3x+2)\\\\= 9x^2+6x+6x+4\\\\= 9x^2+12x+4 \ units^2\\\\\rule[225]{225}{2}

URGENT!!! PLEASE HELP
Molodets [167]

Answer: System 1 has an infinite number of solutions and System II has no solutions.

Step-by-step explanation:

If we look at system 1, we see that if we multiply the first equation by 2 and subtract the y value so that its on the same side as x, the equations are the same. That means that no matter the x or y value, it will be a solution.

If we look at system 2, however, we see that if we multiply the top equation by 3, the equations are the exact same except for the fact that the top equation has a -21. This means that no matter the x or y, there will never be a solution.
