Answer:
Step-by-step explanation:
<h3>- Range is a set of all y-values in a set of coordinate points.
<h3>A linear equation or function always have range equal to set of real number because you can substitute f(x) as any numbers and you'll still be able to solve for x-variable.
An quadratic equation or function may have range equal to set of positive real number or negative real number depending whether if the coefficient of x² is in positive or negative but consider this:
Suppose we have f(x) = x², f(x) cannot be negative number because that'd make the equation not real. Therefore, a quadratic function does not have range.
For an exponential function, it's same as quadratic equation. It depends whether if a base is in negative or positive. You can consider like this:
Suppose we have , f(x) cannot be negative number because there are no x-values that make the equation true. Therefore, an exponential function does not have
range as well.
