No, because there are TWO values of y for a certain value of x

say x=5, then y=2 and y=-2

That does not satisfy the concept of the function.

Answer:

Step-by-step explanation:

To check the given graph of a relation is function or not.

Using graph check for function by vertical line test.

Draw numbers of vertical line. If any of one vertical line intersect the graph at two different points then graph is not a function.

Now check the graph using vertical line.

Draw 3 vertical line. All three vertical line intersect graph at two points.

Please have a look in attachment.

So, The graph of relation is not a function because vertical line test not pass.

Scrat [10]

Answer: 74

Step-by-step explanation:

Substitute x=6 into the expression

(x+4) . 2^3 -6

Add the numbers

(6+4) . 2^3- 6

10 x 2^3 -6

Evaluate the power

10 x 2^3 -6

10 x 8-6

Multiply the numbers

10 x 8-6

80-6

Subtract the numbers

80-6

1. 1 x-200= -200
2. -200 x 1= -200
3. 2 x -100= -200
4. -100 x 2= -200
5. -20 x 10= -200
6. -10 x 20= -200
7. -40 x 5= -200
8. -5 x 40= -200
Hope this helps! :)

What is the slope of the line show belowww

zaharov [31]

Answer:

$\boxed{C.\:\: 2}$

Step-by-step explanation:

The given line passes through the points,

$(x_1,y_1)=(-2,-3)$ and $(x_2,y_2)=(3,7)$ .

We can find the slope using the following;

$m=\frac{y_2-y_1}{x_2-x_1}$

$m=\frac{y_1-y_2}{x_1-x_2}$

Using the first formula;

We obtain;

$m=\frac{7--3}{3--2}$

$\Rightarrow m=\frac{7+3}{3+2}$

$\Rightarrow m=\frac{10}{5}$

$\Rightarrow m=2$

The correct answer is C.

Answer:

Step-by-step explanation:

Function representing the bacterial growth has been given as,

$b_1(t)=1200(1.8)^t$

a). Here 1200 represents the initial number of bacteria taken for the study (1).

b). 1.8 represents the growth factor by which the population of the bacteria is multiplying.

c). Second study is modeled by the function given as,

$b_2(t)=1000(1.8)^t$

Here, initial population of bacteria = 1000

Difference in 1200 and 1000 in two studies means → Second study was conducted on 1000 bacteria while in study (1) number of bacteria were 1200.
