X to the second power equals 14

1 answer:

5 0

X to the second power equals 14 is the same as:
$x^{2}=14$
we can take the square root of both sides to get:
$x= \sqrt{14}$
because we cannot simplify the 14 inside the square root symbol, our final answer is
$x= \sqrt{14}$

if you subtract the least integer from the greatest integer and divide the difference by 3 the quotient is 5

vodomira [7]

Let a and b be integers and b>a, then we can say:

(b-a)/3=5 now multiply both sides by 3

b-a=15

b=15+a

So there are infinitely many pairs of integers that satisfy the conditions given in the problem. For any value a, b will be 15 units greater.

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: $-\infty \: < x < \infty$
