The graph on the top right would represent a function. A function line on a graph includes one line going in one direction. It's not 2 lines, its not just dots either and it definitely isn't in a square because, as I said, it goes in ONE direction. Hope this helped!

Answer:

Graph on top right.

Step-by-step explanation:

We will analyze the graphs given.

A). Graph 1 has two lines showing different points on them and a common point of intersection.

Here lines are representing two functions but the graph is of a system of functions.

So it's not the correct option.

B). this graph is showing a line having points on it with different values of x and y. therefore, this is the correct option.

C). This is the graph representing the system of equations but not the functions.

D). It's a graph of scatter points so not the function.

What are the values of d, e, and f?

Kamila [148]

Answer:

Step-by-step explanation:

The given equation y = 2x^2 -12x - 32 can be factored as follows:

y = 2(x^2 - 6x - 16) = 2(x - 8)(x + 2). Then its roots are x = -2 and x = 8.

Since d > e and 8 > -2, we conclude that d = 8 and e = -2.

We need to find the minimum of y = 2x^2 -12x - 32.

We can do this by finding the vertex: b

The equation of the axis of symmetry is x = - ----------

-12

which here is x = - --------- = 3

2(2)

so f = 3.

Answer choice B is correct.

erica can run 1/6 of a kilometer in a minute her school is 3/4 of a kilometer away from her home at this speed how long would it

nlexa [21]

Answer: 4.5 minutes.

Step-by-step explanation:

1. You have the following information given in the problem above:

- Erica runs $\frac{1}{6}km$ in a minute.

- The school is $\frac{3}{4}km$ away from her home.

2. Therefore, to solve the exercise you must multiply $\frac{3}{4}km=0.75km$ by 1 minute and divide this by $\frac{1}{6}km=0.166km$ , as following:

$x=\frac{(0.75km)(1min)}{(0.166km)}\\x=4.5min$

3. Therefore, the result is 4.5 minutes.
