EXAMPLE 5 Find the inverse of a cubic function Consider the function f (x) = 2x3 + 1. Determine whether the inverse of f is a function. Then find the inverse. SOLUTION Graph the function f. Notice that no horizontal line intersects the graph more than once. So, the inverse of f is...
If f(x) is a one to one function, where f(x)=x2−x+1, then find the inverse of the f(x): A(x−12) B√x−34+12 C√x−34−12 Dnone of theseSubmitIf A=[ 3 4−4−3], find f(A), where f(x)=x2−5x+7. View Solution Evaluate limx→1f(x)−f(1)x...
If a function is one-to-one, then it has an inverse. Some functions are one-to-one by definition, such as linear functions, square root functions, and exponential functions. For other functions, such as trigonometric functions, we need to restrict their domains in order to ensure they are...
Suppose f−1 is the inverse function of the differentiable function f and let G(x)=1f−1(x). If f(3)=2, and f′(3)=19, find G′(2). Derivatives; Inverse Function Theorem: We'll first notice that G(x) is differentiable at 2 and...
To find the domain of the function f(x)=sin−1(√x2−1), we need to ensure that the expression inside the inverse sine function is valid. The steps to determine the domain are as follows: Step 1: Analyze the expression inside the inverse sine functionThe expression inside the functio...
Notethat the inv() function should be used with caution because calculating the inverse of a matrix can be computationally difficult, especially for large matrices. In many cases, it is more efficient and numerically stable to solve linear systems of equations using the backslash operator (\) or...
Example of Finding the Intersection of Two Lines Let's look at two lines:y = 3x + 2 y = 4x - 9 We must find a point (x,y) that satisfies both linear expressions. To find such a point, we must solve the linear equation:
Give the function f and point a below, f(x)=2x4,x≥0,a=6 Find f−1 f−1(x)= ___ Inverse Of A Function Given the function f(x) we want to find the inverse function, f−1(x). 1) Replace f(x) with y 2) Replace every x with a y and...
