How to find the domain and range of 1×2?

Find the Domain and Range F (x)=1/ (x^2) F (x) = 1 x2 F ( x) = 1 x 2. Set the denominator in 1 x2 1 x 2 equal to 0 0 to find where the expression is undefined. x2 = 0 x 2 = 0. Solve for x x. Tap for more steps… Take the square root of both sides of the equation to eliminate the exponent on the left side. x = ± √ 0 x = ± 0.

What is the domain and range of the expression?

The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined. The range is the set of all valid y y values. Use the graph to find the range.

What is f(x) = x2 + 2?

f (x) = x2 + 2 f (x) = x 2 + 2 The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.

How do you find the range of a parabola using vertex form?

Use the vertex form, y = a ( x − h) 2 + k y = a ( x – h) 2 + k, to determine the values of a a, h h, and k k. Since the value of a a is positive, the parabola opens up. Find the vertex ( h, k) ( h, k). The range of a parabola that opens up starts at its vertex (0,2) ( 0, 2) and extends to infinity.

What is the domain of 1/x if x = 0?

Your function is defined for any value of x except the value that will make the denominator equal to zero. More specifically, your function 1/x will be undefined for x = 0, which means that its domain will be RR- {0}, or (-oo, 0) uu (0, + oo).

How to find the domain and range of an algebraic expression?

Algebra. Find the Domain and Range f (x)=|x|. f (x) = |x| f ( x) = | x |. The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined. Interval Notation:

What is f(x) = x2 + 3?

f (x) = x2 + 3 f (x) = x 2 + 3 The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.
