Find the domain for each function:(a) i(x)=x−33 (b) k(x)=5x−2The Domain of a Function:The domain of a function is the input values that we substitute into the independent variable of a function. For some functions, the domain is restricted; for e...
Assume that f is a one-to-one function. If f^{-1}(3) = 2, what is f(2)? Use the definition of a one-to-one function to determine if the function is one-to-one. P(x) = x^2 - 1 Use the definition of the one-to-one...
The root function takes the form root(f(var), var, [a, b]). It returns the value of var to make the function f equal to zero. The real numbers a and b are optional. If they are specified (bracketed), root finds var on this interval. The values of a and b must meet these re...
If the graph fails the horizontal line test, the function does not have an inverse. If the graph passes the horizontal line test, then proceed to Step 2. Step 2: Make a note of the domain and range of the function. Step 3: Return to the given function equation and s...
The square root definition of a given number x is every number y whose square y² = y × y yields the original number x. Note that y² = (-y) × (-y) as well. Therefore, the square root formula can be expressed as: y = ±√x ⟺ y² = x where ⟺ is a mathematical...
