What Is The Domain Of Y X 2 4x 5

Use the graph.

What is the domain of y x 2 4x 5. To better understand why the function is defined for all real numbers see its graph. In this case there is no real number that makes the expression undefined. X in rr complete the square putting the function in vertex form y x 2 2 4 1 y x 2 2 3 hence the minimum of the function is y 3 so we can say that the range is y 3 as for the domain any value of x can be passed to the function so.

All real numbers range. 2 2 start by solving the equation 4 x 2 0 then 2 x 2 x 0 x 2 now select a test point let it be x 0. 6385372 a racket is fired vertically into the air at 40 m s.

Domain ℝ range 9 y 1 0 mccarty lv 4 4 years ago one million c they are valid extensive style as a results of fact they don t have the comparable area which makes it a function and a relation as a results of fact the it could make an equation 2 a the. Locate the vertex of the parabola. The domain is x in 0 4 the range is f x in 0 2 for the domain what s under the square root sign is 0 therefore 4x x 2 0 x 4 x 0 let g x sqrt x 4 x we can build a sign chart color.

In this case there is no real number that makes the expression undefined. Tap for more steps. Tap for more steps.

Thus the graph of y sqrt 4 x 2 is a semicircle with radius 2 and domain. 4 oo lets begin by finding the domain of the function. 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.

In this case there is no real number that makes the expression undefined. The domain of the expression is all real numbers except where the expression is undefined. What is the common monomial factor of 5ts 40t 20 b.
