Y X 2 4 Domain And Range

As a function table and as a set of coordinates.

Y x 2 4 domain and range. So range is y 4 or 4 oo graph x 2 4. To better understand why the function is defined for all real numbers see its graph. All real numbers range. I assume the answer your class is looking for is a domain of all real numbers but there are many possible answers that each effect what your range would be any subset of the complex numbers can be chosen as the domain also there may be more se.

Find the domain and range of following functions. Y x 2 4. In this case there is no real number that makes the expression undefined. To find the range.

A 1 b 0 c 4. Y 4 or 4 oo y x 2 4. Any real value of x i e x in rr or oo oo range. A is positive so the parabola opens upward.

As a parabola and consequently a polynomial the function 4 x 2 is defined for all real numbers there is no point on its domain where the function is undefined. Graph 4 x 2 10 10 5 5 the range is also. 4 oo lets begin by finding the domain of the function. X in rr or oo oo.

Find the domain and range y x 2 4 y x2 4 y x 2 4 the domain of the expression is all real numbers except where the expression is undefined. We know that parabola like a curve. The domain and range of a function is all the possible values of the independent variable x for which y is defined. Here vertex is at 0 4.

The example below shows two different ways that a function can be represented. The vertex 0 4 is the lowest point of the parabola. The parabola giving us all real numbers is the domain. Since a 0 the parabola opens upward.
