The graph of f(x) = X is reflected over the y-axis. Use the graphing calculator to graph this reflection. Which list contains

Maksim231197 [3]

Answer:

Option A.

Step-by-step explanation:

Note : The given function is linear, all options are incorrect for linear function.

Consider the given function is

$f(x)=\sqrt{x}$

For x=81,

$f(81)=\sqrt{81}=9$

For x=36,

$f(36)=\sqrt{36}=6$

For x=1,

$f(1)=\sqrt{1}=1$

It means the given function passes through the points (81,9), (36,6) and (1,1).

If a graph reflected across y-axis then

$(x,y)\rightarrow (-x,y)$

So, the new function is

$g(x)=\sqrt{-x}$

$(81,9)\rightarrow (-81,9)$

$(36, 6)\rightarrow (-36, 6)$

$(1, 1)\rightarrow (-1, 1)$

It means points (-81, 9), (-36, 6) and (-1, 1) lie on the graph of the reflection.

Therefore, the correct option is A.

The probability that a randomly selected point on the grid below is in the blue area is 9/16

DochEvi [55]

Answer:

The correct option is 1.

Step-by-step explanation:

it is given that the probability of a randomly selected point on the grid below is in the blue area is 9/16.

In the given grid we have only two colors that are blue and white.

Let A be the event of a randomly selected point on the given grid is in the blue area.

$P(A)=\frac{9}{16}$

If the randomly selected point on the given grid does not lie in the blue area, it means it lies on white area.

We will calculate P(A'), to find the probability that a randomly selected point is in the white on the grid.

We know that the sum of the probability is 1.

$P(A)+P(A')=1$

$P(A')=1-P(A)$

It is given that $P(A)=\frac{9}{16}$

$P(A')=1-\frac{9}{16}$

Therefore option 1 is correct.

Explain how you can use equivalent fractions to find the quotient of 2 3 ÷ 4.

Virty [35]

Answer:

see below

Step-by-step explanation:

2/3 ÷ 4

We use copy dot flip

The flip means make a reciprocal of the second number

2/3 * 1/4

Multiply the numerators

2*1 = 2

Multiply the denominators

3*4 =12

Put the numerator over the denominator

2/12

Simplify
