How do you find the range given a function?

Overall, the steps for algebraically finding the range of a function are:

1. Write down y=f(x) and then solve the equation for x, giving something of the form x=g(y).
2. Find the domain of g(y), and this will be the range of f(x).
3. If you can’t seem to solve for x, then try graphing the function to find the range.

What is the domain and range of the function f/x 3x 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. The range is the set of all valid y values.

What is the domain of the function f x 3 /( x 2?

What is the range of function 3x 2?

f(x) =3x-2 is defined for all real values of x. If we put any real value , the function will give us an output. and it’s range is also real numbers. So it is defined from R to R.

What is the domain and range of the function x 2?

The function f(x) = x2 has a domain of all real numbers (x can be anything) and a range that is greater than or equal to zero.

What is the domain of FX 3 x?

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.

What is the domain and range of f(x)=2^x?

The domain of a function is usually all real numbers. The range of f (x)=2^x would be the y values. This would include all values that would be the output for the y value. An example of this would be if you used 2 as x then the function would read f (x)=2^2. The y would equal 4 which would be included in the range of this function.

How to find the range of an undefined expression?

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. Determine the domain and range.
