Question

Classwork/Homework:

Which of the following equations represent exponential functions
A. f(x) = 2x3 + 1
B. f(x) = -4*
C. f(x) = 1+
D. f(x) = 3(2)*

Answer 1

Option D, f(x) = 3(2)^x, represents an exponential function.

Step-by-step explanation:

The equation that represents an exponential function is f(x) = 3(2)x. The exponential function has the form y = ab^x, where a and b are constants, and b is greater than 0 and not equal to 1. In this equation, b is equal to 2, which satisfies the condition. Therefore, option D, f(x) = 3(2)x, represents an exponential function.

Answer 2

An object's dimensions are: length of 25cm, wight of 10cm, and height of 15cm. calculate the object's density if its mass is 3000g
