Inverse function

• The inverse of function f

• 1 divided by f(x)

• f raised to the power of -1

• The derivative of f

What happens to the coordinates when a function is reflected over the line y = x?

• No change to coordinates

• x-coordinates and y-coordinates swap places

• y-coordinates become x-coordinates

• x-coordinates become z-coordinates

• 3x

• x^3

• The cube root of x

• x squared

How do you find the inverse of the function f(x) = 7x - 4?

• Divide by 7 and subtract 4

• Multiply by 7 and add 4

• Add 4 and divide by 7

• Subtract 4 and multiply by 7

What is the general strategy for finding the inverse of any function?

• Divide each term by the coefficient of x

• Switch x and y and solve for y

• Multiply each term by -1

• Add a constant to both sides
