Answer:

As below.

Step-by-step explanation:

The -4 shifts the graph to the right not the left.

The second error is the refection is over the x-axis not the y-axis.

Find f(-2) for the function f(x) = 3r2 - 2x +7.<br> 0-13<br> O-1<br> O 1<br> O 23

viva [34]

Step-by-step explanation:

f(x) = 3x² - 2x + 7

f(-2) = 3(-2)² -2(-2) + 7

= 3(4) + 4 + 7

= 23

The graph shows f(x)=(1/2)and its translation, g(x).

san4es73 [151]

The translation of four units up describes the transform function g(x) option first is correct.

<h3>What is a function?</h3>

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

The question is incomplete.

The question is:

The graph shows f(x)=(1/2)ˣ and its translation, g(x).

Which describes the translation of f(x) to g(x)?

Translation of four units up
Translation of five units up
Translation of four units to the right
Translation of five units to the right

The graph is attached please refer to the picture.

We have the equation of the function f(x):

$\rm f(x) = (\dfrac{1}{2})^x$

From the graph, we can see the graph of the function f(x) is shifted up 4 units because the y-intercept of the graph g(x) is (0, 5)

g(x) = f(x) + 4

$\rm g(x) = (\dfrac{1}{2})^x + 4$

Thus, the translation of four units up describes the transform function g(x) option first is correct.

Which formula finds the probability that a point on the grid below will be in the blue area? A grid contains 20 squares. 10 squa

Natali5045456 [20]

The formula that finds the probability that a point on the grid below will be in the blue area is represented by the option:

P (blue) = StartFraction number of blue squares over the total number of squares EndFraction.

The probability = 1/2.

The probability of an event defines the chance of the occurrence of that event. It is given by the ratio of the total number of outcomes favorable to the event to the total number of outcomes in the experiment.

If we suppose an event to be A, the total number of possible outcomes favorable to A be n, and the total number of outcomes in the experiment be S, then the probability of event A can be given as:

P(A) = n/S.

In the question, we are asked to find the formula that defines the probability that a point on the grid will be in the blue area, where the grid contains 20 squares, 10 of them being shaded blue.

We take the event that the chosen point is in the blue area as A.

The total number of outcomes favorable to this event A can be given by n, which will be equal to the number of blue squares = 10

The total number of outcomes in the experiment can be given by S, which will be equal to the number of squares = 20.

Now, the formula for the probability of event A can be written as

P(A) = n/S = 10/20 = 1/2.

The formula that finds the probability that a point on the grid below will be in the blue area is represented by the option:

P (blue) = StartFraction number of blue squares over the total number of squares EndFraction.
