Is the relation below a function? If it is a function, state its domain.

{(0,2),(2,4),(1,7),(2,5)}

A. The relation is not a function.
B. The relation is a function. The domain is {0,1,2}
C. The relation is a function. The domain is {2,4,5,7}
D. The relation is a function. The domain is {0,1,2,4,5,7}

Answers

Answer 1

Answer:

A

Step-by-step explanation:

The relation is not a function. All you need to solve this problem is the following: Relations are NOT functions when the domain values repeat!

Note: The domain is the set of input values. The domain is x, the first number in the pair. For example, in the pair (0, 2), the domain is 0.

In the relation {(0,2),(2,4),(1,7),(2,5)}, 2 is repeated two times, which, by definition, means that the relation is not a function.

cathleen planned to walk her dog for 3/4 f a mile after it started to rain she decided to only walk 1/2 of that distance what fraction of a mile did cathleen walk her dog

Answers

Answer:

Cathleen walked 3/8 mile.

Step-by-step explanation:

Since we are trying to find 1/2 of 3/4, we'll start by converting 3/4 into a form where we can find 1/2, becuase 1.5/4 is not a valid answer.

The simplest form other than 3/4 would be 6/8, we'll get that by multiplying 3 by 2 and 4 by 2. We just need to find half of 6, which is 3. Therefore, Cathleen walked 3/8 mile.

What is the most likely outcome on a chemical reaction in a cell if the shape of an enzyme changes?

A.The enzyme will no longer work with the substrate.

B.The enzyme will be able to bond with a different type of substrate.

C.Different products will result.

D.The substrate can change its shape to match the new enzyme shape.

Answers

However, increasing or decreasing the temperature outside of an optimal range can affect chemical bonds within the enzyme and change its shape. If the enzyme changes shape, the active site may no longer bind to the appropriate substrate and the rate of reaction will decrease.

how do you convert y=-2x²+4x-1 into vertex form

Answers

Answer:

y = –2(x – 1)² + 1  

Step-by-step explanation:

Given the quadratic function, y = -2x²+ 4x - 1:

where a = -2, b = 4, and c = -1

The vertex of a parabola is the point on the graph where the parabola intersects the axis of symmetry. The axis of symmetry occurs at x = h. Therefore, the x-coordinate of the vertex is the same as h.

To find the vertex, (h, k), you need to solve for h by using the formula:    

Plug in the values into the formula:

[tex]h = \frac{-b}{2a}[/tex]  

[tex]h = \frac{-4}{2(-2)} = 1[/tex]  

Therefore, h = 1.

Next, to find the k, plug in the value of h into the original equation:

k = -2x²+ 4x - 1

k = -2(1)²+ 4(1) - 1

k = 1

Therefore, the value of k = 1.

The vertex (h, k ) occurs at point (1, 1).

Now that you have the value for the vertex, you can plug these values into the vertex form:

y = a(x - h)² + k

a = determines whether the graph opens up or down; it also makes the parent function wider or narrower.

If a is positive, the graph opens up. If a is negative, the graph opens down.

h = determines how far left or right the parent function is translated.

k = determines how far up or down the parent function is translated.

Plug in the vertex, (1, 1) into the vertex form:

y = –2(x – 1)² + 1  

This parabola is downward facing, with its vertex, (1, 1) as its maximum point on the graph.
