Rocky thinks of an odd integer adds the next two consecutive integer which of these could be the sum
tekilochka [14]

Answer:

C

Step-by-step explanation:

1. Let x be the odd integer. Let y be the sum.

x + (x + 1) + (x + 2) = y

3x + 3 = y

Adding two consecutive integers to an odd integer will result in an even integer.

So, you can eliminate choices B and D since they are odd.

Lastly, plug in choices A and C for y and choose the answer that makes x an integer.

Choice C would give you the correct result.

3x + 3 = 44562

3x = 44559

x = 14853

Identify the type of function represented by f(x)=1/2(3)^x
Firlakuza [10]

The function represented by f(x) = (1/2)(3)ˣ is an exponential growth

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two numbers and variables.

An independent variable is a variable that does not depend on any other variable for its value whereas a dependent variable is a variable that depend on any other variable for its value.

The independent variable in the function f(c) = 2c + 9 is c whereas the dependent variable is f.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two numbers and variables.

An independent variable is a variable that does not depend on any other variable for its value whereas a dependent variable is a variable that depend on any other variable for its value.

An exponential function is in the form:

y = abˣ

Where a is the initial value and b is the multiplication factor.

If b > 1, it is an exponential growth but if b < 1, it is an exponential decay.

Given the function:

f(x) = (1/2)(3)ˣ

since 3 > 1, it is an exponential growth.

The function represented by f(x) = (1/2)(3)ˣ is an exponential growth
