If the representation is a graph then use the vertical line test. Draw or imagine straight vertical lines going down the graph. If the vertical line only goes through the function line one time then it is a function. For an example, a circle on a coordinate plane is not a function but a wavy line is.
If the representation is a table with points then look at the x values. If x repeats then it is not a function.

Write the first five terms of the sequence defined by the explicit formula an=-4n(n-1)

vladimir2022 [97]

The explicit formula of the sequence is given by a_n = -4n(n-1).

We have to find the first five terms of the sequence.

The first term:

$\begin{gathered} a_1=-4\times(1)(1-1) \\ =-4(0) \\ =0 \end{gathered}$

The second term:

$\begin{gathered} a_2=-4(2)(2-1) \\ =-8(1) \\ =-8 \end{gathered}$

The third sum:

$\begin{gathered} a_3=-4(3)(3-1) \\ =-12(2) \\ =-24 \end{gathered}$

The fourth term:

$\begin{gathered} a_4=-4(4)(4-1) \\ =-16(3) \\ =-48 \end{gathered}$

The fifth term:

$\begin{gathered} a_5=-4(5)(5-1) \\ =-20(4) \\ =-80 \end{gathered}$

Thus, option D is correct.

Which shows the graph of the solution set of y < 1/3 x – 2?

AnnZ [28]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

$y< \frac{1}{3}x-2$

The solution of the inequality is the shaded area below the dashed line

The equation of the line is $y= \frac{1}{3}x-2$

The slope of the line is positive $m= \frac{1}{3}$

The y-intercept of the line is the point $(0,-2)$

The x-intercept of the line is the point $(6,0)$

so

The graph in the attached figure

48 ounce bag of granola each month how many pounds if granola does she eat each year

Dafna11 [192]

Answer:

<em>12 months = 1 year</em>

<u>48 ounce bag of granola per month</u>.

T = 48x

Where 'x' represents the months.

Replace x with 12, because we want to know how many ounces she eats each <em>year</em>.

T = 48x

T = 48(<u>12</u>)

T = <u>576 ounces</u>, she eats each year.
