Graphically Finding Inverses

How could you find the inverse of f(x) graphically? **choose the TWO correct answers**

• Reflect points of f(x) across the line y = -x

• Reflect points of f(x) across the line y = x

• Swap x and y coordinates for each point of f(x)

• Reflect points of f(x) across the line y = 0

Is the inverse of the function shown above also a function?

• Yes

• No

• I don't know

• Maybe?

The equation of f(x) goes through the points (1, 4) and (4, 6).

What points does the inverse go through?

• (1, 4) and (4, 6)

• (-4, -1) and (-6, -4)

• (-1, -4) and (-4, -6)

• (4, 1) and (6, 4)
