Domain and Range of Exponential and Logarithmic Functions Recall that the domain of a function is the set of input or x values for which the function is defined, while the range is the set of all the output or y values that the function takes A simple exponential function like f(x) = 2x has as its domain the whole real lineThe domain is all real numbers, and the range is all real numbers f(x) such that f(x) ≤ 4 You can check that the vertex is indeed at (1, 4) Since a quadratic function has two mirror image halves, the line of reflection has to be in the middle of two points with the same y value Given f(x) = 1x2 To find the range of function Explanation So, the range of a function consists of all the second elements of all the ordered pairs, ie, f(x), so we have to find the values of f(x) to get the required range Given, f(x) = 1x2 Now for real value of f, x2≥ 0 Adding negative sign, we get Or x2≤ 0 Adding

F(x)=x^2-4 domain and range
F(x)=x^2-4 domain and range- How To Given a function written in equation form, find the domain Identify the input values Identify any restrictions on the input and exclude those values from the domain Write the domain in interval form, if possible Example 332 Finding the Domain of a Function Find the domain of the function f(x) = x2 − 1Informally, if a function is defined on some set, then we call that set the domain The values taken by the function are collectively referred to as the range For example, the function takes the reals (domain) to the nonnegative reals (range) The sine function takes the reals (domain) to the closed interval (range) (Both of these functions can be extended so that their domains are the

What are the domain and range of f(x) = (1/6)^x 2? 1 Confirm that you have a quadratic function A quadratic function has the form ax 2 bx c f (x) = 2x 2 3x 4 The shape of a quadratic function on a graph is parabola pointing up or down There are different methods to calculating the range of a function depending on the type you are working withDetermine the domain and range of the function f of X is equal to 3x squared plus 6x minus 2 so the domain of the function is what is the set of all of the valid inputs or all of the valid X values for this function and I can take any real number square it multiply it by 3 then add 6 times that real number and then subtract 2 from it so essentially any number if we're talking about reals when
The domain of the basic exponential function, f(x) = e^x, is all real numbers Translating the function up 2 units doesn't change that so the domain of your function is also all real numbers The range of the basic exponential function is (0, infiI'll be breaking down this question in three parts, 1 When x is positive 2 When x is negative 3 When x is zero In the first case, if x is positive, And since the modulus of a positive number is the number itself, our function becomes, f(x) = x/Answer and Explanation 1 The given function is f(x) = x2 −7 f ( x) = x 2 − 7 Since there are no restrictions on x x , it can take all real values and hence the domain is given by (−∞
