Answer:

Step-by-step explanation:

The easiest way to tell if a relation is a function is to look at the x coordinates. If none of them are the same in the set, then the relation is a function. If any of the x values are used more than once in the set, it is only a relation. This set uses -3 two times, so it is a relation.

Answer:

It is not a function.

Step-by-step explanation:

A function is a relation in which each input x has only one output y.

One visual way to tell the difference is to plot the relation and use the vertical line test.

If a vertical line for a given value of x passes through more than one point, the relation is not a function.

We see in the diagram that the line x = -3 includes (-3,0) and (-3,4), so the relation is not a function.

navik [9.2K]

Answer:

Step-by-step explanation:

Domain of the function will be,

{x ∈ R | x ≠ -2}

Range of the function is,

{y ∈ R | y ≠ -4}

Intercepts of the function,

Their are no intercepts of the given rational function.

Horizontal asymptotes:

Horizontal line parallel to x-axis representing discontinuity.

y = -4

Vertical asymptotes:

Vertical line parallel to y-axis representing discontinuity.

x = -2

No oblique asymptotes.

A bad punter on a football team kicks a football approximately straight upward with an initial velocity of 89 ft/sec.

Andrej [43]

Answer:

See below

Step-by-step explanation:

Vertical velocity will be affected by gravity in this scenario

df = do + vo t + 1/2 a t^2 do = original height = 4 ft a = -32.2 ft/s^2

df = 4 + 89 t - 1/2 (32.2) t^2 df = height

On the way up and the way down, the ball may reach height of 102.2125 ft :

102.2125 = 4 + 89 t - 1/2 (32.2) t2 re-arrange to:

-16.1 t^2 + 89t - 98.2125 =0

Use Quadratic Formula to find t = 1.5 and 4.0 s

A biologist studied how cells grow by adding liquid protein to cell samples. She reported in her study that she divided 3/5 of a

r-ruslan [8.4K]

Answer: $\dfrac{1}{5}\text{ of an ounce.}$

Step-by-step explanation:

Given : A biologist studied how cells grow by adding liquid protein to cell samples.

She divided $\dfrac{3}{5}$ of an ounce of liquid protein evenly among 3 cell samples.

Here , total quantity of liquid protein = $\dfrac{3}{5}$ of an ounce

Total cell samples = 3

Now , Quantity of liquid protein given by her to each cell = (total quantity of liquid protein ) ÷ (3)

= $\dfrac{3}{5}\times\dfrac{1}{3}=\dfrac{1}{5}\text{ of an ounce}$ .

Hence, Quantity of liquid protein given by her to each cell = $\dfrac{1}{5}\text{ of an ounce.}$
