Answer:

see below

Step-by-step explanation:

Answer:

  2a^{\frac{5}{2}}-4a^{-\frac{1}{2}}

Step-by-step explanation:

It looks like you want to expand the expression ...

  \sqrt{a}\left(2a^2 -\dfrac{4}{a}\right)

Use the distributive property and rules of exponents.

  =2a^{(\frac{1}{2}+2)}-4a^{(\frac{1}{2}-1)}\\\\=\boxed{2a^{\frac{5}{2}}-4a^{-\frac{1}{2}}}

_____

The relevant rules of exponents are ...

  √a = a^(1/2)

  1/a = a^-1

  (a^b)(a^c) = a^(b+c)

Relate a vertical line test to understanding functions.
xenn [34]

Answer:

c.

Each vertical line drawn through the graph will intersect a relation in only one location

Step-by-step explanation:

We know that a vertical line test is done to test whether the graph or the given relation  is a function or not and it  states that:

Each vertical line parallel to the co-domain drawn on a graph will intersect the graph exactly once.

i.e. there is a unique image of each pre-image.

Hence, option: C is the correct answer.

c.

Each vertical line drawn through the graph will intersect a relation in only one location.
