F(x)=sqrt(x-2) domain and range
F(x)=sqrt(x-2) domain and range- The domain is the range of x values which give f (x) a value that is unique, such there is only one y value per x value Here, since the x is on the bottom of the fraction, it cannot have any value such that the whole denominator equals zero, ie d(x) ≠ 0 d(x) = denominator of the fraction that is a function of x x − 2 ≠ 0 x ≠ 2F is increasing on 2,0 and decreasing on 0,2 So since f is continuions and différentiable on its domain It has a maximum for x=0 and a minimum at x=2 or 2 and since both f(2) and f(2) are equal to each other, the minimum is f(2)=f(2)=0 The maximum is at x=0 where f(x)=2 so the range is 0;2

We have f(x) = (x 2 9)/(x 3) Domain off Clearly f(x) is not defined for x – 3 = 0 ie x = 3 Therefore, Domain (f) = R – {3} Range off Let f(x) = y Then, f(x) = y (x 2 9)/(x 3) = y x 3 = y It follows from the above relation that y takes all real values except 6 when x takes values in the set R – {3} Therefore, Range (fPrecalculus questions and answers Determine the domain of each of the following functions (a) f (x)= X2 x5 Determine the range of this function by taking the inverse of it and then taking the domain of the inverse which is going to be the range of the f (x) Question Determine the domain of each of the following functions Consider the function, f(x) = x^2 5 The domain is the set of all possible values of x for which this function is defined For f(x) to be real valued, all real values of x are consistent with the definition of f(x) Thus, domain is R, the set of real numbers The range in this case is also R since it is a real valued function Another thing that might be added is that the codomain which is the set of values in the range R to which elements of the domain are mapped Well, for any value of x
State the domain and range of f(x) if h(x) =f(x) g(x) and h(x) = 2x2x 2 when g(x) = 2x 4 Select one O a XER, yER Ob XER, yS 7 8 OC XS , YS 7 8 Od XS , f (x) = √x2 − 4 The best and fastest way is to learn how do parental functions look like and how does the formula look like and then use it The domain square root must be greater or equal to 0 x2 −4 ≥ 0 ⇒ (x −2)(x 2) ≥ 0 That happens only when f (x)>0everything that is above x axis, like this (i usually draw a simple picture of quadratic function)This would include all values that you can input as x in order to make this problem work 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
