Question

What is the domain and range?

a) Domain: all real numbers greater than 1, Range: all real numbers
b) Domain: all real numbers, Range: all real numbers greater than 0
c) Domain: 4, 49, $, -10, Range: X
d) Domain: 4, 49, $, -10, Range: all real numbers

Answer 1

The domain is all real numbers greater than 1, and the range is all real numbers

Step-by-step explanation:

The correct answer is a) Domain: all real numbers greater than 1, Range: all real numbers.

The domain is the set of all possible input values of a function, while the range is the set of all possible output values. In this case, the function has no restrictions on the input, so the domain is all real numbers. However, the range is restricted to all real numbers greater than 1.

For example, if we consider the function f(x) = x + 1, the domain is all real numbers and the range is all real numbers greater than 1. If we plug in different values for x, we will get different output values that are greater than 1.
