What Is The Domain Of Y X 2 1

Use the graph.

What is the domain of y x 2 1. The range is how much the function. Therfore the domain is. This website uses cookies to ensure you get the best experience on our website. This is a parabola equation of which vertex form is y a x h 2 k or y 1 x 0 2 4.

Free math problem solver answers your algebra geometry trigonometry calculus and statistics homework questions with step by step explanations just like a math tutor. Here we can say that if x is a positive. Here vertex is at 0 4. Free math problem solver answers your algebra geometry trigonometry calculus and statistics homework questions with step by step explanations just like a math tutor.

The range is set of all values y which the function takes. So range is y 4 or 4 oo graph x 2 4. This website uses cookies to ensure you get the best experience on our website. The domain of a function is the largest subset of real numbers rr for which the function s value can be calculated.

Solve x 1 0rarrx 1larrcolor red excluded value domain is x in oo 1 uu 1 oo to find range rearrange. If x 0 then you would have to divide by zero which is not defined. Since a 0 the parabola opens upward. In this case there is no real number that makes the expression undefined.

As y 1 is a horizontal line at y 1 horizontally wise it takes all real numbers from to therefore the domain is ℝ. Equating the denominator to zero and solving gives the value that x cannot be. Free functions domain calculator find functions domain step by step this website uses cookies to ensure you get the best experience. In the example value can be calculated for every x 0.

The vertex 0 4 is the lowest point of the parabola. The domain of the expression is all real numbers except where the expression is undefined. The denominator of y cannot be zero as this would make y undefined. Any real value of x i e x in rr or oo oo range.

X in rr or oo oo. Domain ℝ range 1 the domain is how much the function takes x wise in the horizontal axis.
