Question

What is the range of the squaring function

f(x)=x2?
a) All real numbers
b) Only positive real numbers
c) Only non-negative real numbers
d) Only non-positive real numbers

Answer 1

The range of the squaring function f(x) = x^2 is only non-negative real numbers.

Step-by-step explanation:

The range of the squaring function f(x) = x2 is option c) Only non-negative real numbers.

When we square any real number, the result is always a non-negative real number. This is because squaring a negative number gives a positive result. For example, (-3)2 = 9.

Therefore, the range of the function f(x) = x2 includes all non-negative real numbers, but does not include any negative real numbers.
