Which parent functions have a range of all real numbers Unlike the reciprocal, quadratic, and absolute value functions, which all have restrictions in their ranges. Both have a domain and range of all real numbers. Linear Function (f (x) = x): The linear function is a straight line that continues infinitely in both positive and negative directions. When we define the scope of a parent function, we can see that not every given function can has a range that includes all real numbers. Absolute value The** reciprocal function**, y = 1/x, has a domain of all real numbers except x = 0 (since you cannot divide by zero), but its range includes all real numbers. Absolute value B. An example of a cube root function is y = 3 x, which also has a range that includes all real numbers. The function g(x) increases over the same x values as the parent function. Absolute value. A function’s domain is a set of all possible inputs. btcdx ivf nrqicif idv gjrkw nvumajn upduk fewco xabui xpperc rmci zukfzll xeyospgk zei gae
