Question

How do you find the range and domain??

Answer 1

Answer:

In general, we determine the domain of each function by looking for those values of the independent variable (usually x) which we are allowed to use. (Usually we have to avoid 0 on the bottom of a fraction, or negative values under the square root sign).

The range of a function is the spread of possible y-values (minimum y-value to maximum y-value)

Substitute different x-values into the expression for y to see what is happening. (Ask yourself: Is y always positive? Always negative? Or maybe not equal to certain values?)

Make sure you look for minimum and maximum values of y.
