NEED HELP ASAP. The number of views on a viral video each day can be represented by an exponential model in the form y = a ⋅ bx,

Savatey [412]

Replace x and y with known values:

10 = a x b(1) and 20= axb(2)

We can find that a x b must equal 10

Replacing a and b with with numbers we find that a = 5 and b = 2

So now you Ming that in the equation you can find the answer would be (3,30)

Which expression is equivalent to 3-(-5)

Helen [10]

Here is the equation:

$3-(-5)$

When you're subtracting a negative number from a positive number, the sign will change. The - sign will become + and the negative number becomes positive.

$3- \rightarrow 3+ \\ -5 \rightarrow 5$

Here is your new equation:

$3+5$

All you need to do is add 3 and 5.

$3+5=8$

That means your answer is 8.

What are the domain and range of f(x)=[1/5]x

Ber [7]

Answer:

Domain: All real numbers

$(-\infty,+\infty)$

Range: All real numbers

$(-\infty,+\infty)$

Step-by-step explanation:

The given function is $f(x)=\frac{1}{5}x$

This a polynomial function of degree 1.

Polynomial functions are continuous everywhere.

The function is therefore defined for all real values of $x$ .

The domain is $(-\infty,+\infty)$

If we let $y=\frac{x}{5}$

Then, $x=5y$ .

$x$ is also defined for all real values of $y$ , hence the range is also all real numbers or $(-\infty,+\infty)$
