A function is defined as {(0, 1), (2, 3), (5, 8), (7, 2)}. Isaac is asked to create one more ordered pair for the function. Whic

Digiron [165]

Answer:

The correct answer is 2 . (1 , 3)

Step-by-step explanation:

A function is used to denote a particular relationship between variables. They can even be visualized as an input-output machine.

Every function has a domain set and a co-domain set. A function maps elements from domain to the elements of co-domain.

Here the domain can be considered as { 0 , 2 , 5 , 7}.

Here the co- domain can be considered as { 1 , 3, 8 , 2}.

For a function to be a valid function, all elements from the domain should have an image in the co- domain and every element of domain should have exactly one image in the co-domain.

Here the options 1 , 3 and 4 violate the second necessary criteria for the function to be valid.

Hence (1 , 3) is the correct answer.

Given f(x) = x^2 + 2 and g(x) = 2 – x, find a simplified expression for f(2x) + g(3x).

Blababa [14]

Answer:

f(2)+g(3) = 5

Step-by-step explanation:

Given that,

f(x) = x² + 2

g(x) = 2-x

We need to find the value of f(2)+g(3).

f(2) = 2² + 2 = 6

g(3) = 2 – 3 = -1

So,

f(2)+g(3) = 6+(-1)

= 5

Hence, the value of the given expression is 5.

Find the distance between the points (-9,0) and (2,5)

andreev551 [17]

Answer:

sqrt(146)

Step-by-step explanation:

The distance between these two points can be the hypotenuse of our right triangle.

We can create a right triangle with two legs of length 11 and 5. To solve for the hypotenuse, we apply the pythagorean theorem

sqrt(5^2+11^2)=sqrt(146)

I attached a graph to help you visualize the triangle and how it works.
