A function that is increasing on an interval I is a one-to-one function in I Solving Exponential Equations EX) Solve: 81 3 1 = + x EX) Solve 3 2 1 )( 2 e e e
[PDF] Inverse Functions One-to-One Functions
One-to-one functions are functions which do not achieve any value more than ( x) = mx + b, with m = 0 is 1:1, so we take the equation y = mx + b and solve for x:
[PDF] One-to-one function
Finding the inverse of a one-to-one function: 1 Replace f(x) with y 2 Interchange x and y 3 Solve this equation for y The resulting equation is f−1(x) Important
[PDF] 16 One-to-one functions Defining one-to-one functions A function
First, we need to change the functional notation into an equation in x and y The substitution y = f(x) give us y = 9 − x2 Now, we solve the equation for the variable
