Step-by-step explanation: A square root function has a range of y greater-than-or-equal-to 0.
For example, the function f(x) = √x has a domain of x greater-than-or-equal-to 0 and a range of y greater-than-or-equal-to 0. This is because the square root of a positive number is always positive, and the square root of 0 is equal to 0. So, for any value of x greater-than-or-equal-to 0, the corresponding value of y will always be greater-than-or-equal-to 0.
Other functions that have a range of y greater-than-or-equal-to 0 include:
the absolute value function: f(x) = |x|
exponential functions with positive bases: f(x) = e^x, f(x) = 2^x, etc.
any linear function with a positive slope: f(x) = mx + b, where m > 0.
These are just a few examples of functions that have a range of y greater-than-or-equal-to 0.
